How to get interction terms first in a model
Consider the following two specifications of a model: library( splines ) x <- 1:100 y <- rnorm( 100 ) w <- rep( 1, 100 ) A <- factor( sample( 1:2, 100, replace=T ) ) B <- factor( sample( letters[1:4], 100, replace=T ) ) summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B ) ) summary( lm( y ~ ns( x, knots=c(30, 50, 70 ), intercept=T ):A - 1 + B:w ) ) The

2.2.3a PDC Win2K Citrix Profiles
...oaming to Local, then there are no files saved in their Profile Folder on SAMBA but is saved just on the Win2K Server and a WINDOWS\system folder is still created in their SAMBA Home Folder and contains several files. The Profile Folder is not created if it doesn't exist. This may be how Win2K intercts with SAMBA PDC, but the 0700 dir mask is wrong and a user's Profile Folder is created with user:root and group:<user> by default so 0700 would never allow the user access. If you remove 'logon path = ' and don't create a [profiles] share in smb.conf, you get the profiles save...

Dear All, I am writing to ask a clarification on what R, and in particular lme, is doing. I have an experiment where fly wing area was measured in 4 selection lines, measured at 18 and 25 degrees. I am using a lme model because I have three replicated per line (coded 1:12 so I need not use getGroups to creat an orederd factor). The lines are called: "18"; "25";

Lisp-stat and R? [was: Re: Status?]
John Fox (see below) raises important questions for the Lisp-stat community (and perhaps the R community) to consider. This message thread was not cross-posted to r-devel@lists.r-project.org, so I do so now. I have never been an active or particularly adept Lisp-stat programmer. But I have worked on or used several projects for which Lisp-stat seemed the ideal environment-- for implementing
