Hi Tim,
The "scipen" option is the one usually recommended for this. R works out 
how to print a number in a way that is (hopefully) maximally informative 
and minimally long. By "penalizing" this method, you can suppress 
scientific notation most of the time:

print(100000)
[1] 1e+05
options(scipen=4)
print(100000)
[1] 100000

On the R home page is an option "Search". The first search listed is Jon 
Baron's searchable archive messages, functions, etc. and is a good place 
to start. In this case, you would have to take two steps - see the 
"scipen" option mentioned and then look at the "options" help page. 
Usually you will get the answer straight from the search, _if_ you 
choose the correct search terms (life is never simple).
