R v. 1.7.1, Windows 2000. A particular journal wants me to provide scatter plots with no box, but with axes that meet in the lower left corner. It seems as though there must be an easy way of doing this, but my reading the help on plot.default, axis, and box have not provided any clues. I would be most appreciative of any feedback. Thank you, Hank Stevens Dr. Martin Henry H. Stevens,

Hi all, I'm looking for a contributed package that can provide a detailed account of missing data patterns and perhaps also provide imputation procedures, such as mean imputation or hot deck imputation and the like. Is there anything out there? Thanks in advance, David -- =========================================================================== David Kaplan, Ph.D. Professor

Hi all! i have done a fitting of experimental data using optim function and setting up my mixed distribution logliklehood (it is a linear combination of a normal and a weibull distribution). How can i test the goodness of fit? I want to be able to say that my distribution fit the data at 90%, 95% or so on.... thanks in advance, nelson

I have two questions - 1. I am trying to create R png graphs via cron. I have this part working using Xvfb (X virtual frame buffer). One problem that I have, though, is that all the fonts on my graphs get messed up. Anybody have any nija R commands to make all fonts look great? Anybody have any idea how to fix this? So far, no luck on Solaris or Linux making the Xvfb fonts look good. I was

I would like to produce a bar plot with varying-width bars. Here is an example to illustrate: ww <- c(417,153,0.0216,0.0065,556,256,0.0162,0.0117, + 726,379,0.0358,0.0501,786,502,0.0496,0.0837, + 892,591,0.0785,0.0795) yy<-t(t(array(ww,c(2,10)))) barplot(yy[,2*1:5],las=1,space=c(.1,.5),beside=T) produces a barplot of 5 pairs of bars that are of equal width

Hi All, My group is looking for any suggestions on what to purchase to achieve the most powerful number crunching system that $50k can buy. The main application that will be used is R so input on what hardware benefits R most will be appreciated. The requirements are that it be a single standalone server (i.e. not a cluster solution), and it that must be able to run unix/linux. If

...scales, etc. are very important.) I suspect that the support aspect of the Pareto ( i.e. f(x) > 0 only for x >= k ) imposes an indentifiability problem with the mixing proportion parameter. Again, any advice is welcome.

Hello! I have such trouble: I like R, but often I don't have administrator permissions to install R on some (not mine) computers. Could you give me shell on any server with R installed in order to apply R without installing it (simply with PuTTY). Great thanks! -- Best regards, Altshuler Eugeny

Hi, The functions prepanel.default.bwplot() and lpretty() are not running in Deepayan's barley example concerning vertical bars with the lattice function barchart(). Why, is there a restricted use for the package lattice-Internal? Urs Simmen mailto:usimmen at dtc.ch
