How to I "recode" a factor into a binary data frame according to the
factor levels:
### example:start
set.seed(20)
l <- sample(rep.int(c("locA", "locB", "locC", "locD"), 100), 10,
replace=T)
# [1] "locD" "locD" "locD" "locD" "locB" "locA" "locA" "locA" "locD"
"locA"
### example:end
What I want in the end is the following:
m$locA: 0, 0, 0, 0, 0, 1, 1, 1, 0, 1
m$locB: 0, 0, 0, 0, 1, 0, 0, 0, 0, 0
m$locC: 0, 0, 0, 0, 0, 0, 0, 0, 0, 0
m$locD: 1, 1, 1, 1, 0, 0, 0, 0, 1, 0
Instead of 0, NA's would also be fine.
Thanks, Sören
