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

@IsraelLopez-mz7km 3 жыл бұрын

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!

@RosaneRech 3 жыл бұрын

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: kzfaq.info/get/bejne/na6DmJR8q7redGQ.html

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.

@RosaneRech Жыл бұрын

Thanks! I believe you can add the geom_text() to the ggboxplot(). You just need the table with the treatments and correspondent letters.

@federicogarland272 2 жыл бұрын

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.

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!!

@RosaneRech 2 жыл бұрын

Hi Ferga, it is hard to debug the error without the code. Check if your x-axis - genotype - is defined as factor.

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..)`?

Hello, check in your Tk data if there is indeed a column called "quant". If not, check your code in the summarise function. You can find the copy de code for this tutorial at: rpubs.com/RosaneRech/OneFactorBoxplot
