Thanks Duncan, I already installed Rtools but I don't know well how to sort

Do you know what might be going on or where I can find a manual of how to
use Rtools? Thank you
The likely problem is that you didn't give the full path to the tar.gz
file. If it is not in the working directory, that install.packages
command will fail.
An easy way to get the path is to use
filename <- file.choose()
which brings up a Windows dialog; go search for the file, and its name
will be saved in the filename variable. Then use
install.packages(filename, type="source", repos=NULL).
