Initializing vector and matrices
x <- numeric(0)
for (...) {
x[length(x)+1] <- ...
}
works.
You can build a matrix by building a vector one element at a time this way,
and then reshaping it at the end. That only works if you don't need it to be
a matrix at all times.
Another approach is to build a list of rows. It's not a matrix, but a list of
rows can be a *ragged* matrix with rows of varying length.
