similar to: Subset function of lm() does not seem to work

Folks, I asked a question on this mailing list about the subset support of lm(). In a flash, I got three helpful responses from Rajarshi Guha <rxg218 at psu.edu> <http://jijo.cjb.net> Erin Hodgess <hodgess at gator.uhd.edu> and Peter Dalgaard <p.dalgaard at biostat.ku.dk> :-) and it was just great. The mistake I was making was in not understanding the notion of a

I have a data set that is comprised of, for simplicity, a vector of numbers that I want to march across in overlapping windows of say 10 values each, computing a couple of values for each window. Is there a vectorized way to do this, or do I truly need to resort to looping--I think so? Any other clever thoughts? Thanks, Sean [[alternative HTML version deleted]]

Greetings List, I am conducting some large simulations using R. As a result, I get many plots but I'm having some trouble with including some of them in a Microsoft Word document. Can any one tell me the easiest method of having copies of the R-graphs in the Word documents? Best regards Mahmoud [[alternative HTML version deleted]]

Hi I was wondering if there is a permutation test available in R for linear models with continuous dependent covariates. I want to do a test like the one shown here. bmi<-rnorm(100,25) x<-c(rep(0,75),rep(1,25)) y<-rnorm(100)+bmi^(1/2)+rnorm(100,2)*x+bmi*x H0<-lm(y~1+x+bmi) H1<-lm(y~1+x+bmi+x*bmi) anova(H0,H1) summary(lm(y~1+x+bmi)) But I want to use permutation testing to

hi, i am using par(mrow=c(6,6)) function to get 6x6 plots on one screen. the problem that i am having is that the axis tick labels are far away from the ticks and going into previous plots (see attached figure). i need to know how can i reduce the distance between the ticks and their values (y axis values).the part of the code that i am using (after reading in the data) to create the top row is:

Dear Community, (win XP home, sp1; R1.7 -- patched version, binary download, version of lattice obtained with patched version; the following applies to 1.6.2 as well.) The following message was originally composed to seek help. However I have 'hacked' a solution to the following behavior, but none the less someone might find this interesting. To reproduce my 'problem' you

Hi, I need to set ACLs on a samba server, and are using icacls in Win7. It takes several hours to edit an ACL with inheritance, affecting a directory tree with 300,000 files. Server cpu > 70%, client cpu < 20%. Is there a way how I can speed this up? Using "setfattr -R" in Linux does it in approximately 2 minutes, but I want real Windows ACLs. There are 300.000 files in a
