Call Octave functions from Rcpp #13

Closed bhattaa closed 7 years ago

bhattaa commented 8 years ago

Is there a way to call Octave functions directly from Rcpp rather than calling an R function which calls on to RcppOctave?

For the latter, see http://stackoverflow.com/questions/21225662/calling-a-user-defined-r-function-from-c-using-rcpp

Example using inline:

feval <- RcppOctave:::rcppoctave(signature(), '
Rcpp::List args = Rcpp::List::create(10);
SEXP result = CallOctave("rand", args);
return(result);
')

set.seed(1)
res1 <- .O$rand(10)
set.seed(1)
res2 <- feval()
identical(res1, res2)
