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 1.0.4.6 TRUE
Do you want to install from sources the package which needs compilation? (Yes/no/cancel) Yes
