I have to write R code for creating pascal triangle. The code should such that if I enter, eg, i=400 , it should give me a pascal triangle for that.
Can anyone help me?
This StackOverflow thread seems like it might be a useful fit!
thanks. can you also tell me, how to obtain row sum of each row in pascal triangle that is created. the sum should be 2^n.
From the stackoverflow thred @mara linked to:
pascalTriangle <- function(h) { lapply(0:h, function(i) choose(i, 0:i)) }
The run:
p = pascalTriangle(4) unlist(lapply(p, sum)) #[1] 1 2 4 8 16
and compare with
2**(0:4) # [1] 1 2 4 8 16
