I tried to install fBasics package. I believe that is is already installed, but when I type into library() or require() command, it always tells that there is no such package. I attached my error messages below.
install.packages("fBasics")
also installing the dependency ‘gss’
There are binary versions available but the source versions are later:
binary source needs_compilation
gss 2.1-9 2.1-12 TRUE
fBasics 3042.89 3042.89.1 TRUE
Do you want to install from sources the packages which need compilation?
