install.packages("multcomp")

Hi All,
I tried to install "multcomp" package: (install.packages("multcomp")). But encountered the following error:

Warning in install.packages :
package ‘mvtnorm’ is not available (for R version 3.4.2)

install.packages("multcomp")
Installing package into ‘C:/Users/npou797/Documents/R/win-library/3.4’
(as ‘lib’ is unspecified)
Warning in install.packages :

There is a binary version available but the source version is later:
binary source needs_compilation
multcomp 1.4-8 1.4-11 FALSE

Note that my RStudio is the last version. I also tried installing "mvtnorm" first but the following has been shown:

mvtnorm requires R >= 3.5.0 so you would have to update R in order to been able to install it

Its the latest version of RStudio

I opened a new page and now it is working!!!! Weird!!! Anyway, thanks.

Just to clarify, R and RStudio are two separate pieces of software, RStudio is an IDE for the R programming language, so both can have independent versions.

You can download the latest R version from here
https://cran.r-project.org/bin/windows/

Right. Thanks :slight_smile:
