Such a great video! Thanks for putting this together! I love how clear and concise you were with each part! When I was following along I decided (for personal use of scraping imbd) the content rating (G, PG, PG-13, R ect...) was important, but was having some issues adding it to the table since not every movie (content) rating was available. This is what I ended up doing to get around that issue, in case anyone else finds this useful. #Part 1 Select content rating and a variable that does not change (This one was ended up having text of "Rate this") get_rating = page %>% html_nodes(".rate , .certificate") %>% html_text() #Part 2 Make a for loop that adds in 'Not provided" when a movie does not have a rating i = 1 is_null = "Rate this" content_rating = "Rate this" count_rate = 1 for(i in get_rating){ if(get_rating[count_rate] == is_null) { content_rating
Thanks, Man..It's so easy to learn from your videos..and I needed this for my work in the office..You have no idea how much time this has saved me..A subscribe and thumbs up from me!!!!!!!!!!
Hi everyone! Just a question: why my SelectorGadget don't put the code when I highlighting the text is just show "#main a" which is not the code. Anyone can help me please?
@dataslice, i was trying to do this with facebook and google search, like i was searching for dentists in the area, and wanted a list and contact number out of them.. But i only show the div part, of the inspect..
i was hmm, okay, hope this is easier than bs4 in python, and just using the chrome extension with the name variable code .... AWESOME!! that was so easy! Thanks so much
I encountered the same error, but when I tried another page, it worked well. I believe the package does not function directly with pages built using JavaScript.
What do I do if the name field is empty? I followed along with your example and had no issues, but when I tried doing what I needed it for I couldnt get any values in "name"
Hi, i have a question about your video, suppose that I extract the CSV file from a webpage for the engine capacity of different make/models of the cars. now I have make/model and engine capacity . should I then manually search in the CSV file to find each make/model engine capacity related to my dataset? i mean after scrapping, should I manually find data in the CSV file?
Hi DataSlice, thanks for the great tutorial. I was wondering why when I type "View(movies)" I can see the synopsis values but when I export it to CSV, I can't see the synopsis values in the CSV file.
I got the webscrapping part down but the data.frame keeps showing up as an error. I keep getting Error in data.frame(name, year, rating, synopsis, stringsAsFactors = FALSE) : arguments imply differing number of rows: 51, 50
Mhh, I'm getting "Error in open.connection(x, "rb") : HTTP error 403." if I do this in R for the page I want. Using your Google Sheets Tutorial works, however. But since I need nested links that's not really useful. Any ideas?
Thanks a lot Just one question. On my page some of the movies are missing IMBD ratings and hence when i ran the command "(Error in data.frame(name, year, rating, synopsis, stringsAsFactors = FALSE) : " arguments imply differing number of rows: 50, 41" what to do about it?
@Dataslice, I got the following error message when attempting to do the exact same functions: "> year = page %>% html_nodes(".text-muted.unbold")%>% html_text() Error in UseMethod("xml_find_all") : no applicable method for 'xml_find_all' applied to an object of class "function""
Thanks ! this is really helpful. One question about the data, I usually work with spanish web pages and the text have special characters such as á, é, í, ó, ú. These characters do not appear in the CSV file (they appear different as A', Ä, etc). Any idea how to solve this? I used to replace each one manually lol
My IMDB page has 41 titles as confirmed at the top. All columns return 41 elements except (year) which returns 43, this causes a mismatch: "Error in data.frame(name, year, rating, synopsis, stringsAsFactors = FALSE) : arguments imply differing number of rows: 41, 44" This is because the first 3 entries in (year) are: [1] "IMDb user rating (average)"(2)"Number of votes"(2)"Release year or range" I cant see where this is coming from as there are no extra highlights in the gadget selection, is there a way to return only numbers for year)?
Thank you so much for this, well explained!! I have tried this on a website & I get "Error in open.connection(x, "rb") : HTTP error 405." - usually in Python I think they use Hearder or User Agent to bypass this - is there any way to incorporate this in R please?
How can I solve this error? When I run the "movies=data.frame(name,~~)", an error message shows up like "arguments imply differing number of rows: 100,91,1"
how do you deal with this if you don't have a data frame with the same number of rows? This one lined up but it would be easy to get data from a page like this that doesn't.
I got 50 titles & 38 ratings which returned an error, so had to remove rating column to run it. How can missing values be replaced with for instance, N/A?
is there a way to accont for items with a missing variable for example movies that have no cast so that the final output does not result in a dataframe error?
Great video, do you know how i could scrape the entire text from a website ? I was thinking of using it to make wordclouds as shown in your other video.
Hey Nancy -- the rest of the series is up! Part 2 is here: ruclips.net/video/E3pFBp5oPU8/видео.html and 3 and 4 are in the description as well. Thanks for watching!
I ran the code for the title and worked perfectly fine. After I added the same code to get the year, neither year or title worked anymore giving me an error: “ no applicable method for 'xml_find_all' applied to an object of class "function" “
Some of the information that I've tried this on is coming out as double in length. I'm trying to practice this more using data from one of my friends league of legends games. Using leagueofgraphs to get the data. For some reason when I try to get the .gameMode information, data seems to double itself. And when I try to get the outcome of the game, Victory/Defeat, it returns the information as either all Victories with 5 blanks or all defeats with 5 blanks. Does any one have any advice how to fix this problem?
Excellent content! How can I download a multiple tab xlsx file into R from a URL. I know how to merge the tabs together once saved locally, but would like to read them in directly from URL into R.
Hello! I love your videos, very easy to understand even for ppl who have English as a second language like me. Unfortunately when I tried to replicate this script, theres a problem in line 10, when I print line 10 to see its content it shows "character [0]" instead of the information that appears to you (the names of the movies). I tried using both your example and other websites but the problem remains, has anyone else had this issue? Thanks!
Awesome content! Can you help me understand how to download a multi-sheet xlsx workbook from URL into R? It's only two tabs and I do know how to merge the tabs into a single dataframe once downloaded.
First, great tutorial! Thank you. I had a problem creating the data frame because I have a different number of rows in some objects (45 or 50), so this is the reported error: Error in data.frame(name, year, rating, synopsis, stringsAsFactors = FALSE) : arguments imply differing number of rows: 50, 45. Any suggestion on this? Thank you
@@amitkt I encountered the same error, but when I tried another page, it worked well. I believe the package does not function directly with pages built using JavaScript.
This is great thanks! Curious can this be used to scrape a youtube search result (I tried and couldn't get it to work, but ran your imdb code and it worked fine, not sure if it has something to do with the youtube search code or something) Thanks! :)
Yes, unfortunately this method will only work for sites where the content isn't generated dynamically after the page loads (e.g. RUclips). To scrape RUclips, you'd likely need to use the RSelenium library which allows for more advanced web scraping techniques
Hi, thank you so much for your videos. I have a problem when doing so. I use View() to check the output, all columns look great, but when I use write.csv() to export the output, open it, I found some parts are missing, do you know what's the problem? Thank you so much.
That’s odd. Are you sure they’re completely missing? There may be a new line character before the data and maybe your CSV viewer isn’t being displayed? Or maybe try cleaning the text in R (removing all special characters from your data)?
when i web scrap the title names they come in row .title alternating with empty quotation marks.i.e 1."theboys" 2." " 3. "ozark"..kindly help me fix it
Learned more from this than from other 1hr long videos. Thanks for making this video.
This is the first coding project I've ever completed. Your tutorial was extremely intuitive, thank you!
You have such a calming voice and such clear explanations!
Some people can explain things in a neat and simple manner. This video does that
great video, been a SAS user for a while but really getting into R, your videos really help, thank you!
I thought it was really helpful that you explained what the rvest functions are doing! Thank you!
Excellent tutorial, I've been searching for this long time. Thank you so much, bro. Here you have a new sub
I can't believe you have taught me web scraping in 8 minutes! Thanks a heap! Ooh, I subscribed!
Amazing tutorial. Quality content!! Subscribed immediately after I saw this one tutorial. Hats off for the good work.

#Part 1 Select content rating and a variable that does not change (This one was ended up having text of "Rate this")
get_rating = page %>% html_nodes(".rate , .certificate") %>% html_text()
#Part 2 Make a for loop that adds in 'Not provided" when a movie does not have a rating
i = 1
is_null = "Rate this"
content_rating = "Rate this"
count_rate = 1
for(i in get_rating){
if(get_rating[count_rate] == is_null) {
content_rating
Thank you for the very simplified explanation that we are able to understand.

Hi DataSlice, thanks for the great tutorial. I was wondering why when I type "View(movies)" I can see the synopsis values but when I export it to CSV, I can't see the synopsis values in the CSV file.
That’s an odd issue - are you sure the synopsis values aren’t there and just hidden? What command are you using to write to the csv?
@R for students | Dr. Fahad synopsis values are there, just increase the size of excel cell row, you can see it.

hi great video, super useful. Are you able to do a video on scraping behind a login page ?
My IMDB page has 41 titles as confirmed at the top. All columns return 41 elements except (year) which returns 43, this causes a mismatch:
"Error in data.frame(name, year, rating, synopsis, stringsAsFactors = FALSE) :

This is because the first 3 entries in (year) are:
[1] "IMDb user rating (average)"(2)"Number of votes"(2)"Release year or range"
