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?

Pascal's Triangle

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
```
