Hi there, I keep running into errors when trying to install 'haven' on my Mac OS (updated to the newest version of Catalina) on the latest version of R studio. I get this message:
> install.packages('haven') #Allows loading other file types also installing the dependency ‘Rcpp’ There is a binary version available but the source version is later: binary source needs_compilation Rcpp 1.0.4 22.214.171.124 TRUE Do you want to install from sources the package which needs compilation?
