Dear all, for an interactive web application i need to produce a lot of graphics (up to 50) on demand. In the moment i'm using the png format. The png() ...using png(file="Rplot%03d.png", ...); 'plots' ; dev.off()... produces very good graphics. The problem is it takes too long to produce the png files. The bitmap() ...using bitmap(file="Rplot%03d.png",

Dear R users, I want to retrieve "..." argument values within a function. Here is a small exmaple: myfunc <- function(x, ...) { if (hasArg(ylim)) a <- ylim plot(x, ...) } x <- rnorm(100) myfunc(x, ylim=c(-0.5, 0.5)) Error in myfunc(x, ylim = c(-0.5, 0.5)) : Object "ylim" not found > I need to retrieve values of "ylim" (if it is defined

Hi everybody, I have trouble installing my own package under R 2.1.0 (it is fine under R 2.0.1). My OS is Windows NT. I installed my package 'mag' by using menu "Packages/Install package from local zip files....". It's fine (html package description was updated). But when I typed in library(mag) it gave me error: Error in library(mag) : there is no package called

Dear R users, This is more a statistical question rather than an R question. I'd appreciate it if you can give me some suggestions. I have a sample of a time series (sample size 500, fat tail in density). I am trying to calculate the Standard error of standard deviation of a sub-block-sample (sample size 250). I take 100 this kind of sub-block-sample, randomly. For these 100 subsamples, I

Hi everybody, I have trouble in installing packages from source code by following Section 5.1 in manual R-admin.pdf . I am using R 2.1.0 and Win NT. Following the Windows toolset section in the manual, I download the tool set package from: http://www.murdoch-sutherland.com/Rtools/tools.zip and unzip under C:\tools I also downloaded Perl (Windows Port) and installed it.

Dear all, I try to fit least absolute deviation (LAD) regression with R. I couldn't find any command to carry out LAD. What I am doing now is using nlm() and setting the function argument to minimize the sum of the absolute deviation. But for some data it keeps giving out the error message: Error in nlm(absdev, b.start) : non-finite value supplied by nlm. (there is no na in my dataset.) I

Thank you for helping me! I try the "pretty" funtion to select the x-axis position value.Then I use the "format" funtion. xax.pos <- pretty(as.numeric(x$x.name)) format(xax.pos,'%d %b %y') > xax.pos [1] 1091600000 1091800000 1092000000 1092200000 1092400000 1092600000 1092800000 [8] 1093000000 There are something wrong. I found the xax.pos has been changed to

Dear all, I am writing my small working library. I have done most of the work and it seems working well in R. The library name appears in the package list when I type help.start(). Now my problem is about the help files. I have done help file in Rd format and translated it to HTML format (I have a subdirectory (named html) with html file in it and a subdirectory (named help) with .Rd files in

Hi, I am trying to generate plots on our unix (no X) server to be included in our web-pages -> specifically pngs. Without X, png() obviously doesn't work, so I have been trying to define the graphics print device bitmap as described in the help: > bitmap(file="plot.png", type = "png256", height = 6, width=6,res=72) > pie(c(12,5)) >

Thank you ! I run your code. It have a graph with time(date) on x-axis. Thank you very much! Well, Would you like to do me a favor again? Most of times, the x-axis time data is lasted about 3 months. They are too much. I must select some of them marking in x-axis,and they are must reasonable and human-readable. Now I have tried the "pretty " function, But as soon as I run it, the

Hi , When I sort a vector of POSIXct values in R-2.3.0 and R-2.3.1, I get a vector of numeric values and this gets some of my code to crash (class object creation). Is that a R bug? In the mean time. I'll try to override the sort function for the POSIXct objects. Thanks, Patrick Gu?vel Head of quantitative research for electronic trading This message and any attachments (the

I was just wondering if anyone knows what could be the problem with my exporting of plots. Below is the error messages I get when trying to export my plots (all error messages at the same time). I do get a file produced which works but I don't know why these messages appear. Doesn't matter if it is a pdf or a png or any other format I export to. Also, when exporting to png I get

Greetings, I'm trying to debug a simple two-line plot routine in R called test.R: cor(swiss) plot(swiss$Catholic, swiss$Examination) These commands work fine when typed into R. They also work fine when I invoke this routine by the following line into my terminal: R --slave < /Library/WebServer/Documents/gsa/test.R My ultimate goal is to send data to this R routine via a web

Hi, I have a tiny question about the graphics change in R 2.7.0. If I write a script ? la: options(device="pdf") formals(pdf)[c("file","onefile","width","height")] <- list("~/Rplot %03d.pdf", FALSE, 8, 8) plot(3) plot(4) both plots will be written into ONE pdf file. (not two as expected) This worked fine under 2.6.x In R 2.7.0 I
