Feeling very stupid here.

I just want to randomly-ordered some integers, e.g. the numbers 1 to
100, with each element present once only in a random order. 
I suspect I need to randomly sample a population 1-100, remove that
number, then randomly sample what is left until they've all gone,  but I
can't seem to find the right combination of order/sort/sample + runif.

I fear it can't be that hard - has anyone cracked this?
