Hello,
First of all, you should _really_ try to read An Introduction to R, file
R-intro.pdf that comes with every installation of R. The answer to your
question is in chapter 9 Grouping, loops and conditional execution.
It's the very first example:
"9.2.1 Conditional execution: if statements
The language has available a conditional construction of the form
> if (expr_1) expr_2 else expr_3
where expr 1 must evaluate to a single logical value and the result of
the entire expression is
then evident."
Note the "evident" bit.
if(X == 0) Y <- 5/2 else Y <- 7
or, when you become more familiar with R,
Y <- if(X == 0) 5/2 else 7
But do read the manual.
Hope this helps,
Rui Barradas
