Hi! I would like to be able to create formulas automatically. For example, I want to be able to create a function that takes on two values: resp and x, and then creates the proper formula to regress resp on x. My code: fit.main <- function(resp,x) { form <- expression(paste(resp," ~ ",paste(x,sep="",collapse=" + "),sep="")) z <-

...: bwplot(x1,cex=.5,scales=list(cex=0.5),tck=0.5, xlab=list("psi03",cex=.5), panel=function(x,c1){ panel.bwplot(x) panel.points(x[2],0.5,pch=19) panel.text(x[4],0.95,c1[4]) } ) Many thanks, Maria ********************************************************** Maria E Montez Programmer / Data Analyst Center for Health Quality, Outcomes and Economic Research VA Medical Center Bedford, MA

Hi! Suppose I have m objects. I need to find out what are all possible ways I can group those m objects into r groups. Moreover, I need to create a matrix that contains what those arrangements are. I've created code for when r=2 but I've come to a halt when trying to generalize it into r groups. For example, if I have m=6 objects and I want to arrange them into groups of r=2, there

Hi all, Having a very specific problem here: I have a working RedHat9 server running Samba 2.2.7 (the release that comes with RH9), acting as a PDC/File Server to around 15 WinXP Pro client workstations. This all works nicely, apart from our accounting package, Sage Line 50, which depends on its data being stored on a network share. Previously, when the data was stored on a WinNT4 share,
