[R] writing function

[Joshua Wiley]

Hello,

I am guessing by my environment you mean the global environment (where
you normally assign things from the console).  It also looks like you
would like the results of your function call to be a set of new
objects created.  If that is what you are looking for, try:

toto <- function(x,y) {
for(i in x:y){
  assign(paste(c("tot",i),collapse=""), (i*2), envir=.GlobalEnv)
       }
}

toto(1,5) #creates 5 objects in the global environment, tot1, tot2, ..., tot5

HTH,

Josh
