R help - May 2008 - pwr package

Hello,

I'm a new user of the R environment. I need to do some power analysis.  
For this purpose, I installed the "pwr" package from the R window, but
unfortunately something went wrong. The installation of the package  
was successful (I got a message saying so in R) but when I enter a  
function of that package it says that the function does not exist!

I appreciate your help,

Sincerely,
Samar Mouchawrab

see ?library

You need to load the package before R can access its functions.

My guess is that you didn't load it.  

try library(pwr)
