[R] bootstrap help

[casperyc]

Hi,

I have 49 pairs in my data.frame 'data'

x	y
76	80
138	143
67	67
29	50
381	464
23	48
37	63
120	115

...  ...

how do I get a bootstrap sample of size n=50?

i have tried 
sample(data,size=50,replace=TRUE)
and
sample(data,replace=TRUE)

both didnt seem to work (the latter one only return me with 49 sample)

Thanks.

casper
