AS u hve suggested to install Rcpp to resolve ggplot2 error. then again I am getting these errors-
Error : object ‘Rcpp.plugin.maker’ is not exported by 'namespace:Rcpp'
Error: package or namespace load failed for ‘dplyr’
So,can u tell me how to update Rcpp and dplyr to latest versions?
Or any other way to resolve this errors?
