Hi Rosane. It was a clear tutorial. What about adding the letter when you have that treatment*day is significant? ie when you Aa letters describing the significance... Thank you in advance!
Hi, there is no difference to present the letters when the interaction is significant. However, sometimes, instead of comparing all the treatments, it is desirable to compare by rows and columns. This way one can use uppercase and lowercase letters to differentiate rows and columns.
@@RosaneRech Obrigado! I will reformulate my question. The interaction day*treatment is not significant yet day and treatment are significantly (individually). how do I report this with letters in a table showing the means? Thank you in advance! Cheers, G
Using the data summary function, to get the table with factors, means, and sd, I run into an error. Treatments that have a smaller number of observations do not appear in the summary table. Can anyone help?
I have a problem. I want to use the Tukey test to compare the means of 5 groups, only 4 of which have a normal distribution and the others do not. How can I do this?
Are you asking about the plots? They were built in R. Barplots: ua-cam.com/video/BAIMrhZWLe4/v-deo.htmlsi=NVNj1verzAJZ6PXR Scatterplots: ua-cam.com/video/bBKLJ5d-d9U/v-deo.htmlsi=As5lkrr2Dh5u-fkg
I have found this method makes a lot of errors when the comparison is complex. not reliable. ... currently looking for a better method please suggest if anyone knows.
I'm looking for a method to produce graphics for three levels interactions too. . this one only accept two when i insert the third level factor the summarise function cant arrange the data. . Cant fing anything either
You deserve more subscribers and views maybe people are unaware of your content. it's absolutely great.
Thank you! I hope my videos can get to people who can benefit from them!
You are awesome! You saved my seminar presentation for next week!
this was what I needed!
Hi Rosane, many thanks for this. It is a very useful tutorial.
Was really helpful. Thanks!! :)
This helped me so much! Obrigado!
hey that was really helpful..Thanks alot!!...How to make the table with the mean+sd+letters? Does it have a code or do we have to do it manually?

Hi! What code should I input to get CDL if I did Dunn’s Test? Thanks!
A big issue when applying my data, it does not calculate mean and standard deviation, though I am following the same codes and steps
It was very interesting for me. Could you please provide the excel file I mean I want to know the data entry type?
Hi Habibi, you can to download the dataset following the link in the description of the video.
@@RosaneRech , Thank you. I watched the first tutorial and I understood the dataset. It was very helpful for me.

The Kruskal-Wallis test can be used when we cannot assume a normal distribution.
Hi, dear Rosane! Could you please help? Error object 'tukey.cld' not found error, what does it mean?
Hello, please check you loaded all libraries and did not skip any row when running the code.
Which app did you use for this pls?

Please help, I cannot find the library multcompView package in my library
If it is not there, please install the library first using the code < install.packages("multcompView") >

Hi Rosane
While entering the code: tukey.cld
I believe the source of analysis is not addressed properly. Please try replacing anova with anova.rr in the code.
getwd()
setwd("D:/")
library(readxl)
R %
summarise(mean = mean(`Light`, na.rm = TRUE), sd = sd(`Light`, na.rm = TRUE)) %>%
arrange(desc(mean))
# View the data_summary dataframe
