[R] foreach not recognizing functions in memory

[Bos, Roger]

Saskay, 

Thanks so much for that example.  It worked fine on my system.  I didn't
realized SNOW worked on windows.  I will have to read more about it.

Thanks again,

Roger

Try the below code:
==============================

library(foreach)
library(doSNOW)
getDoParWorkers()
getDoParName()
registerDoSNOW(makeCluster(2, type = "SOCK"))
getDoParWorkers()
getDoParName()

testFun <- function(m) {
    out <- m*m
}

out <- foreach(m=1:10, .combine=rbind,*.verbose=T*) %dopar% testFun(m)

helper <- function(i) {

   out <- foreach(m=1:i, .combine=rbind,*.export="testFun", .verbose=T*)
%dopar% testFun(m)  }

 out <- helper(10)
