[R] variables

[forkusam]

Hi,
can someone please help me.
I will give a simple example of my problem. 
p <- function()
{
 i <- 1
 sr <- function(){
 i<-i+3
 i<- sqrt(i)
}
cat(i) 
}
 This is just an example. My main problem is defining
i like a global variable which I can use in the sub-
and main functions without any complicated switches. 
Thanks in advance.
