Bar Charts using ggplot geom_bar - R Lesson 16
HTML-код
- Опубликовано: 3 окт 2024
- In this lesson, I show you how to use ggplot to create bar plots. Specially, we use ggplot geom_bar to create a plot. First, we construct our data using the data.frame function to return a data frame object. Then we explore this data using some plots.
My name is Mark Gingrass, and welcome to my channel.

I will show you how to use the stat=identity as well as the stat=count parameters as well. Finally, we include a fill value to create a stacked bar plot.

Thanks, I always find these videos useful when I need to make a graph
Excellent tutorial--just enough detail to get my plot made. Thanks!
Glad it was helpful! It's been a minute since I played with R so I am due to come back and do some more tutorials.
The best material on barplot in R out there. Thanks a ton!
Thanks for the compliment.

Underrated channel! ❤️❤️ Thanks Mark!
I appreciate that!
Thank you so much!! thanks to this video, I could finish my assignment!
Glad I could help! Did you get a good grade?
@@CradleToGraveR I read the comments too late. I got an A+ then!!
YOU SAVED MY LIFE SIR
thank you, had the error after stat = "count", using count = "identity" then worked 😁
OMG THIS VIDEO SAVED ME
Awesome! This is fun.
Interesting tutorial. I liked the well done explanations and the extra pointers you give. Thank you. I subbed. :)
Thanks I'll make a few more soon. I think I like them being rather short and to the point.
I been looking for what stat = "identity" does. Thanks!
thank you!
how do you fix the aggregation when plotting, without removing data?
geom_bar 3:27 thank you
Love you mate
Muy buen video
I still have errors in my data 😭. I have 1 column date and 2 column of weights (like 0.5 , 0.6 etc). My x axis would be date and my y axis would be stack of the weights (from 2 column). Help please 😭
This is not working for me. Does this work with Macbook pro.?
When you had 3 Marks in the beginning the barchart added up the ages. How do you plot the means, so in this instance the average age of all marks?
You could do df_base
In later tutorials I talk about a function from dplyr package, group_by which would make it easy to group by name, then average the ages if you wanted to.
@@CradleToGraveR Yes, thats exactly what I need. Which tutorials are you talking about exactly? thanks!
@@n0body886 , Look at the tutorials with the word "dplyr" in the title here: ruclips.net/p/PLuak_bGvcWZO0Da0cDVBpDeTQPEWpuvCD
Great tutorial!! Do you know how I'd go about making a grouped bar chart? I've been trying to figure it out for hours but I can't seem to get it and your video has been the closest to helping :)
Did you ever figure it out? I'm just seeing this now.
@@CradleToGraveR Yes I did, I played around with the code till I got it :) Thanks for replying though!
I love you
Gad it helped you out. Ha!
Thank you!
Do you have video lessons № 14 and 15?
Check out the entire playlist, here. ruclips.net/p/PLuak_bGvcWZO0Da0cDVBpDeTQPEWpuvCD
@@CradleToGraveR , sorry, but I can't find video lessons № 14 and 15.
Maybe they were missing?..
P.S. In this list I see a lesson № 13 ggplot (size/alpha...) and next one is № 16 ggplot (geom bar...)
Incredible. CAn you make a video please, how to plot microbial diversity abundance in barplot???
Lol, I can only offer a he basics at the moment. Do you have a link to the data set?
