row. E.g.,

OK, seems like nobody understood my question ;-)
Let's make another example:
I have three variables:
data$male and data$female and data
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 vari
No -- my answer is wrong. I'll leave it to others to correct. Obvious
question to OP: What if more than one of your colors variables
simultaneously have a 1?

Cute answer, Pascal. It may even be the answer to the question the OP
should have asked, but I don't think it answered the question that was
asked. That might be:
c("red"[red], "green"[green], "blue"[blue])

Hello everybody,
I have three variables "blue", "green" and "red" containing values 0 (no)
and 1 (yes).
How can I easily create another variable "colors" with the values "blue",
"green" and "red"?
I hope that you can understand my question and appreciate any solutions or
hints!
Thank you!
David
