[R] Trouble installing pwr package

[Phil Spector]

Brian -
     After you load a package with the library command, you 
can see what objects are available by looking at position 2
in the search path:

> library(pwr)
> objects(pos=2)
  [1] "cohen.ES"       "ES.h"           "ES.w1"          "ES.w2"
  [5] "pwr.2p2n.test"  "pwr.2p.test"    "pwr.anova.test" "pwr.chisq.test"
  [9] "pwr.f2.test"    "pwr.norm.test"  "pwr.p.test"     "pwr.r.test" 
[13] "pwr.t2n.test"   "pwr.t.test"

Those are the functions that are made available by loading the
pwr package.  Do you see something different after you load pwr?
