Is there a native factorial function in R [my searches have been fruitless], or do I need to use gamma() function? ********************************************************************* Dr Peter Caley CSIRO Entomology GPO Box 1700, Canberra, ACT 2601 Email: peter.caley@csiro.au Ph: +61 (0)2 6246 4076 Fax: +61 (0)2 6246 4000 ********************************************************************* [[alternate HTML version deleted]]

...when applied to a nls() object, AIC() doesn't include the estimate of residual error in the number of estimated parameters ... or is my understanding of nls() fitting confused. Any help appreciated. cheers Peter ********************************************************************* Dr Peter Caley CSIRO Entomology GPO Box 1700, Canberra, ACT 2601 Email: peter.caley at csiro.au Ph: +61 (0)2 6246 4076 Fax: +61 (0)2 6246 4000

...should reconsider..." On that note, I think it would be nice when teaching students [with limited stats background] to be able to avoid introducing the gamma function to heighten their confusion! cheers Peter ********************************************************************* Dr Peter Caley CSIRO Entomology GPO Box 1700, Canberra, ACT 2601 Email: peter.caley@csiro.au Ph: +61 (0)2 6246 4076 Fax: +61 (0)2 6246 4000 ********************************************************************* [[alternate HTML version deleted]]

Hi everyone, I''m using a svn pre-commit hook to check manifests for syntax errors. I''ve recently upgraded puppet from 0.22.4 to 0.23.2 and the hook stopped working. I use the following command to parse .pp files: /usr/local/bin/puppet --confdir=/tmp --vardir=/tmp --parseonly --ignoreimport /tmp/$$.pp Now, I make a decision based on the exit code. If 0 then commit, else exit

I have a few different groupings of hosts, and I am wondering what is the best way to organize the node configuration for them. I have a few machines that are VMware hosts, a bunch of VMware guests, and the main admin server which runs a bunch of stuff like puppetmasterd. I''ve got a bunch of classes/*.pp which define configuration for sudo, yum, java, etc. Right now I just have

Hi, I just got my local yum repo setup so that I can use puppet to install packages... and it looks like something is not working. <snip> Tue Sep 19 02:13:05 PDT 2006 Puppet (notice): Starting configuration run Tue Sep 19 02:13:10 PDT 2006 //default/java/package=jdk/ensure (err): change from absent to latest failed: Could not update: Could not execute ''/usr/bin/yum -y install

We haven''t been able to use mongrel for testing yet, but in order not to waste time, we did some performance testing with 1, 2 and 4 puppetmasterd/webrick processes. Attached is an HTML page (ripped from our wiki - not pretty, but reasonably readable) which describes the method and results. If someone feels like making some nice graphs, that would be great. If not, I''ll try to

Since I had my type development epiphany a couple of days ago, I''ve decided to write down my understanding of developing simple types, at http://reductivelabs.com/trac/puppet/wiki/PracticalTypes. I''d appreciate comments from people who already know how to develop types as to correctness, and also comments from people who are new to type development about whether it''s a
