Hi, I've just produced my first lattice plot - the graphic is very impressive, but I only partly understand how it works. I crimped from examples in MASS and the help pages to get most of what I want done. Howver, I find both MASS and the help pages are a little too terse for my needs as a beginner. Can anyone suggest web or print resources for lattice graphics that provide a more thorough

...o have different linewidths for the edges of my graph. I read the documentation but could not find how to control this. On the Graphviz help page I've seen that there is something called "penwidth" but I could not find it in the R edge attributes. Thanks a lot for any help. Adrian Dragulescu

Hello, I want to have a title that will look something like: "Results for \theta=2.1", given that I have a variable theta=2.1, and \theta should show on the screen like the greek letter. I've tried a lot of things: theta <- 2.1 plot(1:10, main=expression(paste("Results for", theta, "=", eval(theta)))) or using bquote plot(1:10, main=paste("Results for

...ot;xyplot", the output is a file that can not be read because it has no pages. With "plot" it works fine. If I do it manually (from the GUI menu), it works even for "xyplot". How can I save it automatically, without the GUI? I use R 1.8.0 on WinXP. Thank you, Adrian Dragulescu

Hello, I'm on Windows, and according to the documentation R searches along the search path when looking for dll's for dyn.load. For illustration, I've copied the XML.dll from package XML in the C:/Temp folder if (file.exists("C:/Temp/XML.dll")) { Sys.setenv(path = paste("C:/Temp;", Sys.getenv("path"), sep=""))

I use R for data management and ongoing data analysis for amongst other things, a multi-center medical research project. I have found Google spreadsheets to be a fantastic way for all collaborators to be on the same page. Furthermore, Google Forms allows one to capture data from respondents and effortlessly write it to a google spreadsheet. Currently, one has to manually download the spreadsheet

Hi all, I've had one of my most miserable R weeks in memory. I'm trying to deal with huge datasets (>1GB each) but am running up against those pesky memory limits. The libraries filehash and g.data are not very suitable for what I need. I haven't gotten into the sql thing yet. Most recently I've been trying to install the new package ff (not yet on the CRAN repository). I
