[R] parsing speed

[Federico Calboli]

Hi everyone,

I have a question on parsing speed.

I have two functions:

F1
F2

As things are now, F2 calls F1 internally:

F2 =  function(x){
if (something == 1){
y = F1(x)
}
if (something ==2){
do whatever
}
}

*Assuming there could be some difference*, is is faster to use the code
as written above or should I actually write the statements of F1 to make
the parsing faster? 

Regards,

Federico Calboli
