[R] Functions within functions in R and S-Plus

Sorry to bother you about a S-Plus related problem, but I hope someone can help.
I have tried to "translate" some code from R to S-Plus (I have colleague that insists on using S-Plus. And yes, I have tried to make him change to R...)
The following code works out fine in R, but in S-Plus (S-PLUS 6.2 for Windows Professional Ed.) I get the error message "Problem in est.theta(x): Object "func" not found ". I have tried to keep most of the structure in my original problem (but simplified it!), so the code could seem a bit strange. I suspect that this has something to do with different scoping rules in R and S-Plus, but still I have not found a workable solution in S-Plus.

mainfunc <- function(x){

est <- function(x,par){

func <- function(par,x){


est.theta <- function(x){

    optimize(func,lower=-10, upper=20,x=x)$minimum     }



x <- 1:10

Any help is greatly appreciated.
