Set the "R_HOME" environment variable and package installed, but precompiling didn't work correctly.

You need to build RCall after setting the R_HOME not just recompile it. Please also note that R_HOME should point to a R installation location rather than the executable.

Hence, the correct commands could look like this:

ENV["R_HOME"]="/your/R/installation/directory/path"
using Pkg
Pkg.build("RCall")
using RCall
