Subject: Re: [R] Using cbind to merge different variables
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
