Description: R/C++ interface classes and examples
The Rcpp library maps data types betweeen R and C++, and includes support
for R types real, integer, character, vector, matrix, Date, datetime (i.e.
- POSIXct) at microsecond resolution, data frame, and function. Transer to and
+ POSIXct) at microsecond resolution, data frame, and function. Transfer to and
from simple SEXP objects is particular easy. Calling R functions from C++ is
also supported.
