How would you program Pascal's triangle in R?

Question

I am reading, on my own (not for HW) about programming, and one exercise involved programming Pascal\'s triangle in R. My first idea was to make a list and then append thin

Answer 1

using a property of the Pascal triangle:

x <- 1
print(x)
for (i in 1:10) { x <- c(0, x) + c(x, 0); print(x) }

I suppose this code is very fast.
