I know I should not mix base plotting functions with grid/lattice functions, but I have used a "quick-and-dirty" trick of par(new=T) in the past for annotating a trellis-drawn graph in various versions of S-PLUS. The sequence goes something like this: > windows(width = 5, height = 5, pointsize = 10) # open up the device > xyplot(y ~ x) > par(new=T) > xyplot(y2 ~ x) >

R Users: How can I catch R errors and depend on this error call other R functions in Perl? The foolowing is the error message when I use perl call R. Error in nls(modout ~ exp(-b1 * modin)/(b2 + b3 * modin), trace = F, start = c(b1 = 0.005, : singular gradient Segmentation fault Thanks, Zhongming

R v. 1.7.1, Windows 2000. A particular journal wants me to provide scatter plots with no box, but with axes that meet in the lower left corner. It seems as though there must be an easy way of doing this, but my reading the help on plot.default, axis, and box have not provided any clues. I would be most appreciative of any feedback. Thank you, Hank Stevens Dr. Martin Henry H. Stevens,

Hello all, I want to read a table from a given web page. If I do something like > str="http://www...." # this is the web address > aux1 <- url(str,open="rt")# open connection > aux2 <- readLines(aux1) # read web page aux2 contains the html file. I want to extract the table from the html file. Is there a function html2R, the opposite of R2html?

Thanks very much to Paul Murrell and Frank Harrell for addressing my original query (repeated at end of this note). Paul's helpful suggestion with print.trellis and its more= argument, followed by trellis settings, works precisely as I needed. > # snipped from Paul's reply: > p1 <- xyplot(y ~ x, ylim=c(-5, 5)) > p2 <- xyplot(y2 ~ x, pch=16, ylim=c(-5, 5), ylab="

Hi All I am really very interested in starting to use R within our company. I particularly like the open source nature of the product. My company is a medical research company which is part of the University of London. We conduct contract virology research for large pharma companies. My question is how do we validate this software? I wonder if anyone else has had the problem and might be able to

I have two questions - 1. I am trying to create R png graphs via cron. I have this part working using Xvfb (X virtual frame buffer). One problem that I have, though, is that all the fonts on my graphs get messed up. Anybody have any nija R commands to make all fonts look great? Anybody have any idea how to fix this? So far, no luck on Solaris or Linux making the Xvfb fonts look good. I was

Dear all, I am trying to create a web interface using Perl-CGI to call R plots and to display them. The following codes works perfectly fine when I copy and paste into the console directly or if I save it into script.file and then R --no-save < script.file producing the graphs. jpeg("graph.jpeg", width=400, height=400) plot(rnorm(100)) dev.off() Now, I put the line system("R

Hi all I am doing some stats work for a group of biologists who require windows metafiles (*.wmf) for their publications. To create these, I appear to have two choices: 1. Restart my machine in Windows and use savePlot 2. Keep my machine in linux, save as another format, then convert. I'd rather stay in linux; but how do I get wmf files? I looked at using ImageMagick's convert,

Hello, I have a concrete statistical question: I have a sample of an univariate mixture of an unknown number (k) of normal distributions, each time with an unknown mean `m_i' and a standard deviation `k * m_i', where k is known factor constant for all the normal distributions. (The `i' is a subscript.) Is there a function in R that can estimate the number of normal distributions k

Dear all: First, apologies for cross-posting multiplicities and for a query that is more analytically related than S-language related. The bottom-line wish is: Could you please provide and advice, references, etc on S software approaches for fitting a distribution with density: p*g(x) + (1-p)*f(x) where g(x) is the familiar lognormal 2-parameter density and f(x) is Pareto as defined below?

Hi Does anyone know of any R routines to send emails from R, under Windows? I thought about writing such a facility using the R(D)COM package to drive e.g. MS Outlook, but I don't want to reinvent the wheel. I have found a function Sys.mail in the library syskern, but this only works under Unix by shelling out a mail command. Thanks, David

Dear colleagues: I use R 1.9.0 on Windows XP. One of my common tasks is to get R graphs into Word documents. A open windows() device, almost always trellis.device() for me, provides great convenience with the right-click shortcut menu item "Copy as metafile". I typically have the History > Recording feature turned on as well. Since upgrading to 1.9.0, I have experienced an

Dear r-help, Having used S-Plus for many years, it has been suggested to me that I could benefit from learning R. A question to this end, though. Would all of my existing S-Plus arrays, functions, and so on have to be re-created from scratch in R, or is there a way to copy them into the .Rdata directory? The answer to this question has major implications for the extent to which R is

Hi everyone, I'd like to call R from a PHP script to draw graphs (using data selected from a MySQL database) on Windows 2000. I think what I need to do is: 1) Install R for Windows 2) Install Perl 3) From PHP make a system call to Rcmd.exe 4) ??? Does this seem right and/or possible? I'm not sure how PHP can "receive" the graphic generated by R. I have Apache/PHP/MySQL

Hi there. as a newbie I figured out the basics of R but when it came to graphic output it was a bad surprise. All but the X11 device do not function properly. Most of them generate an empty file and pdf() produces non valid output (gs and acroread as well). Very annoying, because I have to write a report. I got the recent stable binary rpm (v1.6.2) from CRAN on a SuSE Linux 8.1. Any help? CU

Hi, I was just looking at the "CRAN Daily Package Check Results" [http://cran.r-project.org/src/contrib/checkSummary.html], and realized there are 1000 packages on CRAN as of today (look at row 3 in the table below). Yet another quite extraordinary milestone in R history. Last updated on 2007-04-12 11:48:32 Results for installing and checking packages using the three current flavors
