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.
Perhaps the actual output would help here.
Strangely, I never get access to the pwr object in R.
Not familiar with the package, but is there such a thing
as the 'pwr object'?
It does not appear that there is such a thing. There is an entry for
the package overview:
help("pwr-package", package=pwr) # and ...
help(pwr.f2.test, package=pwr) # says its result is :
"Object of class '"power.htest"', a list of the arguments (including
the computed one) augmented with 'method' and 'note' elements."
I tried installing it to /usr/local/lib/R/site-library and
~/R/x86_64-pc-linux-gnu-library.
So, where does .libPaths() tell you it knows about?
I also tried installing it with R CMD INSTALL pwr.
But if library(pwr) succeeded, then the package is installed. What is
the problem you (Brian) are facing?

MacOSX 10.5.8/R2.11.1/pwr-1.1.1
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 :-)
