Dear R-gurus: How do I overlay 2 plots in the same frame in R? Or, if I have a histogram, and I want to plot a function in the same frame - how do I do it?

Dear R-guRus: I would like to pass variables to a function in R in "by reference", e.g Fortran style. For example, suppose I have the following code x<-c(1:10) y<-1 MyFunc<-function(x,y) {y<-sum(x); return(NULL)} MyFunc(x,y) print(y) in this case print(y) will produce "1" instead of 55 (which is sum(x)) - how do I make sure that afte the function is run, y

Dear R-guRus: I have 2 questions 1) I have 2 variables, e.g. x<-5; y<-"Char" How do I create a new variable which would have both these values in a string (e.g. "5Char", or "5 Char", etc ) ?? 2) if i have an array x[1:100], and I do x[x==345.123], how do I get position j in the array of those x[j] which are equal to 345.123 ? Thank you very much, Vlad.

I would like to plot two different scatterplots in the same frame (say with different colors) but everytime plot is called a new frame is created.

I'd like to search the r-help mail archives. However, it takes a long time to load the html archive for my searches. Is there a simple way to download the entire http://cran.r-project.org/doc/mail-archives/r-help/ archives in text format so I can execute simple grep searches? thanks, Mike -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list

It would appear to me that there is a bug in the postscript device when multiple pages are required. Line widths can be only 1 after the first page. I have not seen reference to this as a problem before. test.device <- function() { # looks like the problem is in the postscript device postscript(file = paste("Test.ps"), horizontal = F) on.exit(dev.off())

Hi, Another question about graphics... Suppose I have: par(mfrow = c(4, 6)) which will set up a figure region for 24 plots. But, I actually only need 23 plots. In fact I wrote a little function, foo.plot, which will draw all the 23 plots at once with: foo.plot(x) where x is a data frame. Now, suppose I want to draw several set of these 23 plots, but want to put them all in one postscript

Hi all, I want to use a fourth plot on a page as a "map" of how to interpret the previous three plots - so the x axes are all the same but I want the y axis on the fourth plot to have no graduations or numbers - is this possible? I had a look in Peter's book and the help stuff but couldn't see anything. Thanks, Phil. -- Philip Rhoades Pricom Pty Limited (ACN 003 252

Is there a limit on the number of pages that can be in a pdf file? I am using pdf() (on R version 1.4.1, running on Red Hat 7.1 on an Intel box) to create a large (> 300 pages) file of diagnostic plots. If I plot every figure I want to include (364 pages, according to Acroread ver. 5.0.5), neither xpdf on Linux nor Acroread ver 5.0.5 on Win98 can render the file. xpdf give the error message:

I've been trying, without much success, to change the properties of the device on the Windows (1.3.0) version of R. What I'm trying to do is move the plots further away from each other on the device (which will hopefully translate to the same on the printout) and get the top plot closer to the top and the bottom closer to the bottom. I've sized the device to 8.5x11 using

Negative numbers in (encapsulated) postscript generated by R loose their sign when opened in Adobe Illustrator 8 (french). This was so in 1.5.x and remains in 1.6.0. I suppose that this is a known issue, although it is rather a flaw in Illustrator than in R, if my analysis of it is correct. I sent a lengthy mail containing a solution (ISOLatin1Encoding has to be redefined) to the r-help mailing

Dear R-guRus: I am stuck with the following problem in R: Let's say i have a data.frame with columns X,Y & Z. X is a column of numbers, Y is a column of N factors "A", "B", "C", "D", etc and Z is a column of n factors "a", "b", "c", etc if i do MyLm<-lm(X~Y*Z - 1) i get all N coefficients for Y-factors, but only
