R help - Apr 2003 - Odd and Even

Hi,
I'm trying to create a function, jim(p) which varies
depending on whether the value of p is odd or even. I
was trying to use th eIf function, but i cant work out
a formula to work out if p is odd or even.
Thanks,
Dave

if(p %% 2) "odd" else "even"

Or if you are very lazy there is is.odd() and is.even() in library sma.

Thank you for you previous help :)

I now need ot know how i can name a specific operation
inside a function. i am using the if(cond){}else{}
construction and would like to name it. However if i
do assign a name to it and then call it later onm in
the function, it is not recognised. does any one have
any idea why?
Thank you,
Dave

Functions can be defined within (i.e. local to) functions.  If you are 
more specific about what you did, it would be easier for others to help.

Try this

ifelse(p%%2 == 1,"Odd","Even")
