Dear Professor King, Is there a difference between $\operatorname{P}$, $\operatorname{Pr}$, and $P$? Geoff

no idea. $P$ is in math mode. $\text{P}$ puts it in roman. Gary On Sun, 26 Mar 2006, ghumphr(a)fas.harvard.edu wrote:

Prima facie, $\text{Pr}$ is a probability density, $\text{P}$ is calculated from a CDF, and $P$ is a generic probability function. I hope that all is well with you. Quoting Gary King <king(a)harvard.edu>du>:

New subject: [gov2001-l] R and snow

Hi all, does anyone have any experience with parallel computing with R? I've tried to get the snow package to work, but keep getting the same error message when trying to load it:

...

Error in library(snow) : 'snow' is

not a valid package -- installed < 2.0.0? Any suggestions? (I'm using R 2.2.1) Thanks, Holger Gary King wrote:

New subject: [gov2001-l] R and snow

Hi Holger, That message generally means that the package wasn't installed properly. install.packages("snow") library("snow") works for me, but I only have R for Macs, and also unix. (version 2.2.1 with both) What platform are you using? Windows? I don't have much experience with R for Windows, but I've heard of problems with installing some packages properly with it. Maybe try the R for Windows faq on cran? -delia Quoting Holger Lutz Kern <hlk23(a)cornell.edu>du>:
