Hi I'm developing an R package that needs to execute some code written in pari/gp.
I've used this before from an R package (elliptic) but the interface is very basic: the R function creates a string such as the following: string <- echo ' ellwp ([ 2+0*I , 0+2*I ], 1+0*I )' | gp -q And then system(string) returns the output from gp which then needs to be text processed (translating "I" to "i", etc). I don't think this approach would work under Windows. Does anyone have any experience of calling pari/gp from R? Or any ideas for a more portable method than the one above?
