Re: [R] scope of variables in R

-BEGIN PGP SIGNED MESSAGE- Hash: SHA1 Hi, A) you should give and return the variables through input/output parameter of the functions, e.g. pwtset <- function(n, inout) { if (n < 100){ inout$ncof <- n } else { inout$ncof <- n -100 } ... return(inout) } ford <- function

[R] scope of variables in R

I need to allocate (using C nomenclature) a set of "global" variables, some integer scalars and some double vectors. I have placed the name of such variables in the file containing the main script and the called functions: # --
