Dear R users,
I guess, I have a quit simple problem, but I'm not getting the solution.
I create a matrix like this:
test <- matrix(seq(1,3,1),ncol=5,nrow=3)
then I want to create one vector, consisting of every row of the matrix.
My first idea was to do this with a for loop.
op <- vector()
for (o in 1:3){
op[o] <- as.vector(test.id[o,])
}
The results should be like this:
[1] 1 1 1 1 1 2 2 2 2 2 2 3 3 3 3 3
thanks!
