HI,
May be this helps:
set.seed(45)
dat1 <- as.data.frame(matrix(sample(0:1,100*5,replace=TRUE),ncol=5))
dat1$Newvar <- 1*(!!rowSums(dat1))
A.K.
Hello.
I have a problem combining a number of variables. I have five
columns with binary variables with the values 0 and 1. I would like to
combine them into just one binary variable with 1 whenever just one of
the other has value one, and 0 if none of them have value one.
How can I do that?
I tried to use cbind function, but for some reason I get results
1 even though all of the varuables included = 0 and for some rows I get
2. I tried changing the deparse.level but that doesn't seem to be the
problem.
I hope someone can help.
Kind regards
