Hi @ramgouveia,
If you installed rtools42 to the default directory ("C:\rtools42" on Windows) then R should find it automatically when you try to install a package from source code.
rtools42 is not required when installing packages from pre-compiled binary files (that's why doing it that way is easier). The binary version of the latest iteration of any package will propagate through the CRAN mirrors over a period of several days.
