In case you really want to use the apply variety, here is another one,
sapply(fac,function(x)ifelse(test/x<1, 1, 0))

hi all, sorry for this basic question, I think I know I should use ?apply, but
it is really confusing me...
I want to create a matrix by comparing two vectors. Eg:
test<-seq(1:10)
fac<-c(3,6,9)
and i want to end up with a 10*3 matrix with a boolean that tests if test<fac,
so something like:
1 1 1
1 1 1
0 1 1
0 1 1
0 1 1
0 0 1
0 0 1
0 0 1
0 0 0
0 0 0
I can't find the solution without using a loop...
