I am having a peculiar problem with installation of packages. I am trying to install the package "maptools". This is what I get. install.packages("maptools",depend=T) Warning in install.packages("maptools", depend = T) : argument 'lib' is missing: using /usr/local/lib/R/site-library Warning: unable to access index for repository http://cran.wustl.edu/src/contribdependency ''maptools'' is not available This is a machine running debian sarge. The http_proxy is correctly set. I am able to download the package by using wget. I also tried starting R with (R http_proxy-http://my-proxy/). That does not help either. I have R 2.4.1 on my debian system. Will be grateful for any help. Vikas
