It's my first post on the blog.
I recently updated R to version 4.0.1 and, when computing an ANOVA post-hoc with Tukey, I ran into an error message. Being more specific, I use the cld function of multcomp package and, even if the package is correctly installed, the function does not work:
cld(means, Letters = letters, reversed = T, adjust = "TUKEY")
Error in cld(means, Letters = letters, reversed = T, adjust = "TUKEY") :
could not find function "cld"
I specify that I am using the same code I was using with the previous version of R (3.4.2), which was working correctly in this release.
Can anybody help me?
Thank you very much!
