Hello, I was wondering if anyone has run across this problem in the past and might be able to suggest a solution. I did a review of the FAQ's link trying to find a topic that closely related to the experience I was having, however I didn't see anything that might help in diagnosing the problem.

Hi, While installing precompiled packages I often get warnings like the one in the subject. I usually ignore them, but I still do not understand why windows packages are build with unreleased versions of R. Is there some way to get packages build under R-2.2.0? What are potential problems that can result from that version mismatch? My system: winXP R version: 2.2.0 Jarek Tuszynski

I have some questions and observations about these: Will these replace manually setting options(CRAN), which doesn't work in R-2.1.0? In R-2.1.0, setRepositories() looks to see if options("repos") contains a CRAN entry and will not override that CRAN entry even if the $R_HOME/etc/repositories file (which setRepositories reads from) contains a CRAN entry. Why is this? The user

Folks: A minor (R 2.2.0) Windows package install annoyance, but I can't figure out how to fix it. If someone could tell me how or point me to the appropriate docs, I would appreciate it.

Hi, Have just recently downloaded R version 2.14.1 and can't install packages (Code below), 32bit version on windows.

Any ideas on how to rectify the problem would be greatly appreciated Cheers >

Hi guys :) I'm dealing with this problem, perhaps conceptually not that complex, but still - I'm stuck. Two columns, values 1<x<10, only integers. I want to check when the first column's index is identical to the second's (and vice versa). If that's true, I want to add a further column with value 1 (if true) or NA (if false).
