[R] warnings messages from R when returning nothing

Hi : I have old Splus code that I am trying to turn into R
( I am using windows Xp and R 2.20 ) and I am getting a warning 
from one of my statements because the behavior of R is different from Splus.

below, tempdata is a matrix of numbers and 
I have the following command which basically runs through the columns and returns the minimum index of the column
where an NA occurs.


The problems seems to be that, if the column doesn't have any NAs,
then I get the following warning : "no finite arguments to min :
returning inf". So, consequently, I get a lot of warnings
anfd -infs.

I dont have Splus right now but from the code I have under
the above command it looks like Splus returned NA rather than -inf and didn't give any warnings.  This would be the the way
I would prefer it to be handled. So, I was
hoping that there is there a way to avoid getting these 
warning and get the behavior that Splus gave me by modifying
the code or setting something in the environment ?
Thanks a lot.
