Thank you for this great video. Very clear and easy to follow. It has helped me produce some beautiful boxplots today! Please do more!
Thank you! Will do!
EXCELLENT explanations !!!
Great video! I’ll put this lesson in practice right away!! Thanks again!!
Thanks!
Que hermosa profe! muchas gracias! salva una tesis
This was very helpful! Thanks a lot!

muito bem explicado
Thank you very much !!!
Glad it helped!
thank a lot a beatifull skills from beatifull Lady!
Love the accent and explanation.
Thank you! 😃
Thank you
Hi Rosane, could you please a video on how to add significant letters on box plot for the split-plot data with main factor and sub-factor? Thank you.
Beautiful. Thank you
Mam, you are amazing
Great video. Would be possible to do the same on a boxplot for a two way ANOVA?
Amazing video! Thanks so much. I have tried using the same method for Kruskal wallis and dunn test. But couldnt get the result. Im stuck at cld. Could you please help me out with this? Thank you.
Thank you for useful video. Could you apply example data file?
Best tip
Happy to help
Certainly a great video!!!! However, I'm facing some problems with plot generation. At the end of line 39 you introduce 'y=quant', what is this? When I run the function for plot, it's generated an error 'quant object not found'. I would appreciate information about it. Thanks beforehand
Interesting. Could you demonstrate it from the raw data? dip? vjust?
Hi, interesting tutorial. I'm sorry how can I understand the letters? I mean it's been a while since my last class for statistics. But I got significant differences come up from p-value, right? How can this be related to those letters? Thanks!
Hi Israel. Yes, the letters come from the p-value and follow two simple rules:
- the highest mean receives the letter "a"
- means that have no significant difference receive the same letter.
You can take a look at this tutorial: ruclips.net/video/gHSe1KFTzD0/видео.html
Is it possible to do this with a Non-parametric anova and a Dunn’s test posthoc? Standing by
Thanks
Hi Rosane,
been following closely but i somehow cant go past this error
Error in UseMethod("group_by") :
no applicable method for 'group_by' applied to an object of class "character"
i have reached the Tk stage.
Thanks
Perfect! How about adding significant values to a faceted Boxplot
Great video and lesson. In which rstudio version does the multcompView package exist?
I believe you can install the multcompView package in any of the recent versions of R.

What if I have produced 50+ ANOVA boxplots, using GGBOXPLOT() and now I just need to add the CLD? Can I add CLD to ggboxplot? I would prefer to just go into my code and build cld/tk tables and apply those labels to my existing plot. I was able to follow along with this tutorial making a new boxplot from my dataset using this method. Great video, the best R tutorial I have seen online to date.
Thanks! I believe you can add the geom_text() to the ggboxplot(). You just need the table with the treatments and correspondent letters.
what can I do if I have several continuous variables? The letters don't sort themselves accordingly since they are being sorted out for each variable's mean instead of the treatments.
great video but my cld didnt appear in the table after i run the "print(tk)" :(
Hi
I got the following error on the last line of code....Genotype is my x axis , everything worked perfectly, till the end...Could you give me some advice?
Don't know how to automatically pick scale for object of type data.frame. Defaulting to continuous.
Error in FUN(X[[i]], ...) : object 'Genotype' not found
Thanks, the video was great!!
Hi Ferga, it is hard to debug the error without the code. Check if your x-axis - genotype - is defined as factor.
Tengo como errror " Error in fortify(data) : object 'Tk' not found" agradeceria su ayuda
Don't know how to automatically pick scale for object of type data.frame. Defaulting to continuous.
Error: Aesthetics must be either length 1 or the same as the data (4): label
Run `rlang::last_error()` to see where the error occurred
plz resolve this error. i got this in last line
I am trying to add the letters but my R seems not to be adding them?
Hai it is very helpful video. I need small clarification...
When I changes axis from X to Y and Y to X, the geom_boxplot (aes( fill = factor (..middle..)) argument is not functioning and I got an Error code showing object middle is not found.
Please help me to fix the issue.
Is it working without the `aes( fill = factor (..middle..)`?
@@RosaneRech Yes, it is working.
I would have to take a look on your code to figure out what is happening.
I have just published the tutorial on my website, where you can copy the code to reproduce the tutorial.

I hope it helps you in finding the error.
@@RosaneRech Will follow madam
How to make boxplot of three factor experiment ?
How can I organize my data on my excel table?
Thanks a lot! This tutorial is easy to follow
This does not work with my dataset unfortunately
I got this Error in FUN(X[[i]], ...) : object 'quant' not found. Can you help me to solve this issue???
Me too
Hello, check in your Tk data if there is indeed a column called "quant". If not, check your code in the summarise function.
