Read DataFrame from R in RCPP
I would like to read data Frame from R to RCpp and later do processing as existing data Frame from R is Huge & to avoid lot execution time. I come across Rcpp::DataFrame::create function but not sure how we can read existing Dataframe from R and call within Rcpp.
Do we have any function in RCPP as Rcpp::DataFrame::Read?
Thank you for you suggetion.
