[R] functions sample() and S.SI()

[Lourdes Molera]

Hello,
I need to select a sample from a small population using simple random 
sampling without replacement. I've found two possibilities in R, the 
function sample() and the function S.SI() in the package 
TeachingSampling, but I don't know which one is better.
Can someone help me?
Thank you
