I'm trying to update my "perturb" package to get rid of some small warning
messages. The examples in "perturb" use the "Duncan" dataset from the "car"
package and I have "car" installed in R. But when I run "R CMD check", I get an
error message
> require("car")
Loading required package: car
Warning in library(package, lib.loc = lib.loc, character.only = TRUE,
logical.return = TRUE, :
there is no package called 'car'
> data(Duncan)
Warning in data(Duncan) : data set 'Duncan' not found
This is very strange, the example works fine if I just run it in R. This is the
example from the perturb.rd file:
\examples{
require("car")
data(Duncan)
attach(Duncan)
m1<-lm(prestige~income+education)
...
I'm using R 2.11.1 under Ubuntu 10.04. Perhaps the problem is related to the
packages being installed in my home directory. I've create an ~/.Renviron file
with
R_LIBS_USER="/home/john/lib/R/library"
I've also tried creating an environment variable "export
R_LIBRARY_DIR=/home/john/lib/R/library/" before running R CMD check. That made
no difference. Can anyone point me in the right direction? Do I have to install
packages in R_HOME?
