R help - Jul 2012 - If equal statement for character objects

I have a data frame (trans)
123     P
143     z   ...ect

I want to write a statement that says:
if ((trans[i,2]="p")&(trans[1+1,2]="z")){....

but I get the warning message that states:
 operations are possible only for numeric, logical or complex types

Any ideas?
Thanks

1. Please read an Intro to R before posting further. In your previous
post you confused "=" with "==". These and other basic
matters are
discussed there, so you can save yourself -- and this list -- a lot of
time and aggravation by familiarizing yourself with it.(Unless this
was just a typo).

2. I presume that you read the ?all.equal Help -- the part about not
using all.equal directly in if() expressions -- and adjusted your code
accordingly?

3. Please post directly to this list, not on Nabble, as context is
lost for those who access R-help directly, which means also that you
reduce the likelihood of a helpful reply.
