system command to a specific shell (bash)
I need to run a bash command, but when you call system() the default shell is sh (see my sessionInfo below). I found the shell command ( http://www.stat.ucl.ac.be/ISdidactique/Rhelp/library/base/html/shell.html) but it seems to be disappeared in current versions of R? I am running all this from R CMD BATCH with "system" calls to other R scripts. For a little more info, I'm generating sphinx documents (a python documentation library) through R and need to...

Full_Name: Anton Zgonc Version: 1.8.1 OS: Linux RH 9.0 Submission from: (NULL) (193.2.208.9) The SearchEngine, accessible through generated documentation by help.start() like: file:/tmp/Rtmp2085/.R/doc/html/search/SearchEngine.html or on WWW: http://www.stat.ucl.ac.be/ISdidactique/Rhelp/doc/html/search/SearchEngine.html works only in Netscape 4.7x.

search site for R (http://finzi.psych.upenn.edu)
My search site, http://finzi.psych.upenn.edu, has had several problems recently, all my fault, for which I apologize.

Trouble phrasing an R command that will run the model i need (ANOVA, nested)
...F-test for "foresttype"? I sought help for this, and it was suggested to me that i give up trying to use "aov()" at all, and do it all using the "lme()" command in the lme4 package.

My first try was: >library(lme4) >lme(yproductivity ~ foresttype+crosstype, data=productivity, yproductivity >~ region+crosstype+experiment) (I excluded interactions and "...
