Dear all, I found that the plotmath seems won't work on xlab in plot (and other plot functions including matplot, contour, ...): > plot(1:10, 1:10, xlab=expression(alpha)) the plot shows nothing for x-label.

Dear R-Friends, How can I calculate a double integral like \int_a^b \int_c^y g(x, y) dx dy where a, b, c are constants, g(x, y), e.g., g(x, y) = tan(x + y). I tried to nested integrate() and adapt(), but none of them working, seemingly due to the limits can not be specified constants. Best regards, C.

Dear R-Friends, Sorry to bother everyone with my earlier question: "Do we have similar R function to work like Minitab's INDICATOR?" I found the way to make things work: e.g., > x <- c(2,2,5,3,6,5,NA) > model.matrix(~ factor(x) - 1) factor(x)2 factor(x)3 factor(x)5 factor(x)6 1 1 0 0 0 2 1 0 0 0

Dear R-friends, As the binary windows version of R being distributed, what is the correct way to install contributed packages without using winst.exe as before? The answer in "R for Windows FAQ" says: "You can install pre-compiled packages either from CRAN or from a local .zip file by using install.packages: see its help page." But the information available in

Hello, First a disclaimer :) I am very new to using R. I am generating some plots and eventhough I can get colored output in the encapsulated postscript files in the simplest of commands (e.g. plot(1:10,1:10, type="l", col="red") ), it does not work for the particular plots I want. It works on the screen. Here is an example taken out from "Mixed-Effects Models in S and

Dear R-friends, After change (and saved) font style to "bold" in GUI preferences from menu-bar Edit, R 1.2.0, Win98, the "buflines" in the file Rconsole changed to "bufiles" and that causes error in invoking R next time. Is this a bug? Merry Christmas & Best regards, C. Joseph Lu Department of Statistics National Cheng-Kung University Tainan, Taiwan

Please forgive me if this has been asked and answered, since I just can't find out. As I try the example given in the help page of xyplot() as follows: > library(lattice) Loading required package: grid Attaching package `lattice': The following object(s) are masked from package:base : levels > data(quakes) > xyplot(long ~ lat , data = quakes) R crashed!

Dear R users: How can I use panel.qqmathline, in package lattice, to add straight lines onto the plots generated by qqmath? I read help pages of qqmath, panel.qqmathline, xyplot, ..., but just can't one example that shows how to make it work. For example, > data(sleep) > qqnorm(~ extra | group, data=sleep, aspect=1) how can I use panel.qqmathline? Thanks very much for your help,

Hello useRs, Is there a way to write code in R to ring a bell in Windows? Best regards, C. Joseph Lu Department of Statistics National Cheng-Kung University Tainan, Taiwan ROC _______________________________________________________________________

Since I just experienced another crash on R 1.4.0 for Windows (this time is on plot(x, y) after using gls() of package nlme) and am told (thanks Andy) that is might due to the "official" version of binary copy. I am also told that "The one provided by Prof. Ripley is known to work. This has been asked several times on the list." Then, I am wondering when the

Dear R-friends, I have whole bunch of objects, say, A, B, ..., Z, all of them are "list" and haveing "Title" (a character string) as their first element. E.g., > A$Title [1] "Airplane Component" What I like to do is to find a way to printout all the Titles at one time. I tried the following: > paste(LETTERS, "Title", sep="$") ->

Hi all I am using R to produce postscript pictures via the postscript command. I have never had any problems... until now, when I want to inlcude my .ps file is a LaTeX document *without* a white background. (If it's important, I'm using the prosper class with the whitecross option, so the background in blue.) I would like my .ps file to have a white background. If I read the help

On a RedHat 7.3 system with R-1.6.1, I did this > x11(width=3.5,height=4,colortype="gray") Then plotted (with matplot) a nice looking no-color graph on the screen, then I did this: > dev.copy2eps(file="test.eps",height=4,width=3.5) I was surprised that the output in the eps file included the colored lines from the plot, even though the screen device was set to

Dear R-users, The numerical integration example given in Gentleman and Ihaka (2000), "Lexical Scope and Statistical Computing," JCGS, 9, 491-508, is very interesting and helpful in understanding how lexical scope is about. However, I got some questions that I just can't figure out. First all, allow me to copy the two functions given by the authors: midpoint <- function(f, a,

Hi all I wish to create a ps file of a picture produced in R. With my limited R, I see two ways: 1. Print direct to the postscript device 2. Print to the screen, and save to ps using dev.print. I want a white (not transparent) background. Option 1 above works fine, but 2 does not: even when I say I want a white background, I get transparent; perhaps I misread the help files. Here's some R
