Hi all We are pretty new to R here and trying to achieve something that we believe is possible but it?s not easy to work out how to do it. We are producing scatterplot matrices for e.g. 10 variables. What we would like to do is superimpose 2D kernel density estimators on top of each plot so that we end up with a scatterplot matrix of 2D kernel density (contour) plots. The kernel density plots

Greetings all, PGF is a package for LaTeX which works with both ps and pdf output without any nasty hacks like pictex. Is there any technical reason why there could not be a PGF graphic device for R? If not, I'm going to try to throw one together. Any tips for getting started? Cheers, Caleb

Dear R People: I have used the "latex" function from the Hmisc package and it is just great! However, I have a new question regarding that function: is there an option for summary(lm(y~x)), please? There are options for different types of objects, but I didn't see one for that. Maybe I just missed it. Thanks in advance! R for Windows Version 2.3.1 Sincerely, Erin Hodgess

Dear Folks-- Is there a data frame analog to sparse matrices? I am working with a panel data set that has a large number of variables that are redefined repeatedly or exist for only a few years (out of 48). In my current structure, where variables are columns and rows are years, more than 90 percent of the cells and more than 3/4 of the total size of my file are NAs. I am wondering if there is

Dear all, I'm trying to improve the documentation I provide my R packages, and to that end I'd like to find out what you think is great R documentation. I'm particularly interested in function documentation, but great vignettes, websites or book are also of interest. What is your favourite bit of R documentation, and why? Thanks, Hadley

Dear list members, I can't figure out how get 'xyplot' or 'dotplot' in the 'lattice' package to respect the 'lwd' value for specifying the border with for *symbols* (for lines it works fine). Example: ----- # Base graphics works fine (gives a 'fat? circle) plot(5, cex=10, pch=21, lwd=10) # But 'xyplot' or 'dotplot' doesn't

Hi WizaRds, I'd like to overplot UK fuel consumption per quarter over the course of five years. Sounds simple enough? Unless I'm missing something, the following seems very involved for what I'm trying to do. Any suggestions on simplifications? The way I did it is awkward mainly because of the first call to plot ... but isn't this necessary, especially to set limits for the

Hello, A made a xyplot using the lattice library in R (latest version). The publisher of our paper has requested: 1. all tick marks should point inwards instead of outwards. 2. All lines should be thicker (lines, axes, boxes, etc. Everything). Lines is easy...I used: lwd=1.5 but what about the lines of the axes, and the lines that build up the plot itself?....? Any
