Hi all,
I'm having trouble getting access to the pwr. This is on Ubuntu Lucid Lynx,
64 bit.
I'm installing pwr via packages.install('pwr'), and loading it via
library(pwr), both of which appear successful.
Strangely, I never get access to the pwr object in R.
I tried installing it to /usr/local/lib/R/site-library and
~/R/x86_64-pc-linux-gnu-library.
I also tried installing it with R CMD INSTALL pwr.
I have also tried installing it on my mac mini running Leopard but it can't
even find the packages object, and CMD INSTALL pwr returns "invalid package
'pwr'".
Expedient help would be appreciated :-)

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?
