OK, seems like nobody understood my question ;-)

Let's make another example:

I have three variables:
data$male and data$female and data$transsexuals

All the three of them contain the values 0 and 1.

Now I'd like to create another variable data$sex. Now in all cases where
data$female==1 the variable data$sex should be set to 'female', all in all
cases
where data$male==1 the variable data$sex should be set to 'male' and so
on...

Thank you!

David
