Last year I have written some functions for my then supervisor using
Rcpp and inline, which worked fine. Recently my supervisor got a new
Mac, and the functions don't work anymore.
After some trying I found at least one thing that wasn't working
properly. As an example see this function:
library("inline")
library("Rcpp")
fun <-cxxfunction(, '
NumericVector foo(3,1.0);
return wrap(foo);
',plugin="Rcpp")
fun()
This returns the vector (1,1,1) for me, but numeric(0) for my
supervisor (compiling seems to go fine and functions work with objects
like double). I have no idea what is going wrong. I realize this is
probably a very system-specific problem that is hard to "fix" through
mail, but I am hoping that you might have some ideas on what might go
wrong or a place to start.
Below are some system specifications.
Best,
Sacha Epskamp
