[R] Error in autoloader

[Peter Ho]

Hi,

After installing the latest versions of lme4, Matrix, VR on a Debian 
Box, I have run into a problem. When I use library(lme4) on R Version 
2.1.0  (2005-04-18) I get the following error message:

 > library(lme4)
Loading required package: Matrix
Error in autoloader(name = "confint", package = "MASS") :
        autoloader did not find 'confint' in 'MASS'

An example of the complete session is given at the end of this email. A 
search in the docs.
At present I have 3 directories where packages are kept, as I use 
apt-get install "r-cran-package_ name" when one is available in Debian 
and when it is not R, R CMD INSTALL package_name. This gives me the 
following directories when use help.start():

(1) Packages in /usr/local/lib/R/site-library  (packages installed by R 
CMD INSTALL)

(2) Packages in /usr/lib/R/site-library (packages installed with apt-get 
install)

(3) Packages in /usr/lib/R/library (base install with apt-get install)


Matrix, lme4 and other suggested packages were first installed with R 
CMD INSTALL.  and can be found in /usr/local/lib/R/site-library.  After 
the error occured, I updated VR with apt-get install (found in 
/usr/lib/R/library) and got the same error message.

Installing a second version of lme4 and matrix with apt-get install puts 
these packages in /usr/lib/R/site-library and gives the same error as 
before.

Looking at the MASS no function 'confint' exists, only confint.glm, 
confint.nls,confint.profile.glm and confint.profile.nls

Can anyone suggest a solution to the problem or why I am unable to 
access lme4 or as the error statement suggests, a problem with the 
Matrix package and Mass?



Thanks

Peter
