[Gretl-users] R-functions update

[Allin Cottrell]

The facility for defining and calling R functions in gretl has now 
been extended to support strings on input and output. (Previously this 
worked only for scalars and matrices). This is in git, and will be in 
the 2018a release. Trivial example follows:

<hansl>
set R_functions on

foreign language=R
   strfun <- function(s) {
     s <- paste(s, "blossom")
   }
end foreign

string s = R.strfun("cherry")
print s
</hansl>
