I am using Linux Mint and trying to install the adagio package on RStudio (Version 1.2.1335) and the following message is appearing:
> install.packages("adagio")

Warning in install.packages :

Finally, I would like to know if anyone could tell me which command should I run to know the version of R installed on my machine.
