Hi folks, I have R x64 2.11.1 installed on Win 7 64 bit which is running as VM (guest) on Oracle VirtualBox. Is there any difference between it and R on Linux? I can install another R on Debian 5.04, also running as VM. TIA B.R. Stephen L __ R-

[R] Colours on conditional levelplots in package "lattice"

I am having difficulty in getting the colours on a conditional levelplot in the package lattice to work as I want them to - I wonder if someone could help me. The colours do not completely agree with the colour key. Here is a specimen example. require(lattice) col1 <- c (1.37,2.35,0.20,1.85,0.

Re: [R] Pausing script to allow user input from keyboard.

Don't cut/paste; 'source' in the script. readLines is trying to read from stdin which is where the commands are being read from. Using 'source' avoids that problem. You can also look at some examples I have seen using tk/tcl where you can bring up a window for user input. On Fri, Aug 6, 2010 at
