I have performed ANOVA (1 way) followed by Turkeys Multiple comparison in R console. Now I need to denote letters to the means in table to show if there is any significant difference between the means bases on p-adjusted value of Turkeys HSD test. I can do it manually but will be time consuming. Is there any command or package in R to denote the letters for showing significance based on Turkeys HSD test. Kindly help me in this regard.
I find it most instructive to give a graphical summary in a HSD plot:
plot(TukeyHSD(aov(model)))
The 95% confidence intervals that do not intersect the zero-line indicate p < 0.05
For examples see: http://biometry.github.io/APES/Stats/stats13-anova.html
The assignment of letters to treatments after pairwise comparisons or similar analysis is sometimes called a compact letter display.
The multcompLetters function in the multcompView package can convert a matrix or vector of p-values to a compact letter display.
The rcompanion package has a function cldList, that allows for some variants in the inputted comparisons.
Examples are attached.
