You mean you've never typed 'ls' instead of 'ls()' and discovered this
for yourself? I still do it all the time, and I've been using S/R for
ten+ years :)
Ah, maybe you're not a Unix person ('ls' is the command to list files).
Just type a function name to see the source, or to see how it
disappears into R's internal code. You can also do print(rpois), but
you'll see for rpois it disappears into internal code:
function (n, lambda)
- now you need to get the full source code for R and look into C code.
