How to generate a compact letter display for pairwise TukeyHSD

由 时光总嘲笑我的痴心妄想 提交于 2021-01-07 03:24:52
问题 I'm having trouble generating a compact letter display for my results. I've run an ANOVA followed by Tukey's HSD to generate the p values for each pair, but I do not know how (or if it is possible?) to assign letters to these p values to show which pairs are significant from each other. csa.anova<-aov(rate~temp*light,data=csa.per.chl) summary(csa.anova) TukeyHSD(csa.anova) This runs the tests I need, but I don't know how to assign letters to each p value to show which pairs are significant.

问题 I get a strange error when running the Tukey test. I hope somebody is able to help me with this as I tried a lot. This is my dataframe: Name Score 1 A 2.29 2 B 2.19 This is my Tukey Test code: #TUKEY HSD TEST tukey = pairwise_tukeyhsd(endog=df['Score'].astype('float'), groups=df['Name'], alpha=0.05) tukey.plot_simultaneous() plt.vlines(x=49.57,ymin=-0.5,ymax=4.5, color="red") tukey.summary() This is the error: <ipython-input-12-3e12e78a002f> in <module>() 2 tukey = pairwise_tukeyhsd(endog=df[

问题 I have followed the answer from this question: Tukey test results on geom_boxplot with facet_grid It is great, but what I would like is to compare the facets between them as well. In other words, letter order all of the results first then divide it into facets (I have both horizontal and vertical facets). How can I do this? Also, how can I reorder the letters to start from "a" in the first variable in the first facet, and then "b" the second variable and so on? I tried the following, and it

问题 I have a dataframe called data. I have created a function that loop thorugh a list of variables and creates a linear model for each of them using lapply. This method is based on this post. library(datasets) testDF <- data.frame(Salaries) #creates list of variables varListTest <- names(testDF)[3:4] #creates a model for each of the variables in question model<- lapply(varListTest, function(x) { lm(substitute(i~Rank, list(i = as.name(x))), data = testDF)}) #output model lapply(model, summary)

问题 I'd love to place letters representing the results of a Tukey's HSD on boxplots I make in ggplot. I am aware of other posts (Tukeys post-hoc on ggplot boxplot, Tukey's results on boxplot in R) but in my case, I work with facet_grid and I am not sure how to proceed. As I am creating a lot of boxplots, I would love to have something automated. Any tips to help me get me started would be greatly appreciated. Thanks a lot library(multcompView) library(ggplot2) #sample dataframe df <- data.frame

I am working on placing letters representing the results of a Tukey's HSD on a boxplot that I've made. I've found a description of how to do it here: r-graph gallery , but I am getting an error after I run the function.
