R Question

mlr package installation error

When I try to install

package, I get this error message

Package which is only available in source form, and may need compilation of C/C++/Fortran:


These will not be installed


Your issue happened once to me, if I remember right, you need Rtools as others have said. Notice, though, Rtools is not a package, it's an official maintained package-building application.

You must download it from the release page: Building R for Windows.
