I wish to save a scatter plot comprising approx. 2 million points in order to include it in a LaTeX document. Using 'pdf(...)' produces a file of size about 20 MB, which is useless. Using 'cairo_pdf(...)' produces a smaller file, around 3 MB. This is still too large. Not only that the document will be too large, but also PDF viewers choke on this. Moreover, Cairo has problems

Hello all, I am using quartz (on OS X obviously) to produce PDFs and PNGs from my plots, for later inclusion in LaTeX. I am typically using something like: plot(0) dev.print(quartz, file="foo.pdf", width=5, height=3) dev.print(quartz, file="foo.png", width=5, height=3, dpi=72) I want the sizes of the PDF and PNG to be *equal* in *inches*, which works with dpi=72. However,

Hi, Just wondering whether anyone had thought about moving the R sources to a "distributed" version control system such as Bazaar, Git or Mercurial. These new generation systems make it easier to work on feature branches, allow working offline, are very fast, etc. Some projects that have moved to Git are Linux Kernel Perl Ruby on Rails ... http://en.wikipedia.org/wiki/Git_(software)

Hi, I am getting unexpected behaviour from aggregate.ts(). The 'ndeltat' argument is effectively being reduced by 1 in some cases, even when it is an integer, with the result that the blocks to be aggregated are not of the expected size, and also that the end() of the aggregated series is much later than the end() of the original series. rawts <- ts(rep(1:10, each = 5), start = 1) ##

Someone inquired on StackOverflow about apparently non-deterministic graphics behaviour in R. I noticed that they were using cex="*" and discovered some potentially weird behavior. On repeated runs of the same code I can get different PNGs. If I set the number of runs high enough, I seem to be able to get R to hang. If I do a single version plotting to an interactive graphics

Dear list, I would like to export a matrix to a TXT-File by using write.csv (not necessarily). Is there a way to add a header (with additional informations concerning the project) spanning multiple lines to this file before the actual data are listed up? Should look like this: date: filename: number of permutations: ------------ data (as a matrix) Any suggestions? Thnx in advance.

Dear R gurus.. Is it possible to control span settings for different values of a grouping variable, when using xyplot? an example code shown below d=data.frame(x=rep(sample(1:5,rep=F),10),y=rnorm(50),z=rep(sample(LETTERS[1:2],rep=F),25)) xyplot(y~x,data=d,groups=z,panel=panel.superpose,panel.groups=panel.loess(span=c(2/3, 3/4,1/2)) or something like..

I have noticed that xloadimage rpm is not in centos 5.1 I use the command "xview -identity" to get the size of gifs, jpgs, and pngs. xview is part of the xloadimage package. The command "file filename" also reports sizes for gifs and pngs BUT not for jpgs. Is there an alternative command to use to report gif jpg and png sizes? I thought about just getting an older

I am trying to create a map with selected states based on highest to lowest mean cost. The following code properly selects the correct states, and the legend is properly color coded with ranges, but the colors per range does not match the state colors. I need help getting the state colors to match the ranges outlined in the legend. I have tried ordering the mean amounts and this correctly creates

I have a folder full of pngs and jpgs, and would like to consolidate them into a pdf with appropriate title and labels. Can this be done via R ? _________________________________________________________________ Easily publish your photos to your Spaces with Photo Gallery. [[alternative HTML version deleted]]

I've just been trying to post-process some R-created heatmaps using Inkscape, but I can't get them to display correctly in that software. To reproduce: library(grid) r <- as.raster(matrix(runif(25), 5, 5)) pdf("test.pdf") grid.newpage() grid.raster(r, interpolate = FALSE) dev.off() This figure should be a five by five block of grey squares. This is what I see in the R GUI

Hi, I wonder if anyone knows how to control color and darkness of the background grid generated by ' type = c("g", "p") ' in a lattice plot (e.g., in xyplot). The documentation does not seem to offer a way to change them. Thanks a lot! Wen

A colleague is interested in modifying the ylim definition for individual panels of a common bwplot plotting statement. Is there an approach to modifying the bwplot function to allow for a dynamic ylim range given different panel factors ? He is using R 2.6.2 on a Linux distribution running from a CD. Thanks for the assistance. Steve Steve Friedman Ph. D. Spatial Statistical Analyst

Hello, I am trying to use ≥ symbol in the Trellis custom strip. The ascii ALT Key for this symbol is 242. However, when I try "\242 90 kg" I get the ¢ symbol in the trellis custom strip. Can some one kindly help me? Thanking you in advance, MNS [[alternative HTML version deleted]]

I am trying to add labels equal to the value in a levelplot. I believe that panel may be the way to go but cannot understand the examples. In the following example: X,Y,Z A,M,100 A,M,200 B,N,150 B,N,225 I would like to label each of the rectangles 100,200,150 and 225 and colour according to the value The colouring is achieved by levelplot(z ~ x *y , data) but then I get stuck with the labels

Hi all, I'm working on some plots using lattice (R 2.10.1), and have entered the polish phase. I've produced a satisfactory pair of xyplots ( http://imgur.com/EyXGi.png), but would like to align the y-axes of the top and bottom plots. I assume that I need to adjust axis padding or something, but I can't figure this one out. Thanks for any help! Dave -- Post-doctoral Fellow

Folks: I would like to write two lines of text in two different font sizes (or faces or ...) as the title ("main") of a trellis plot. The following code does it, but not well: xyplot((0:1)~(0:1), main = textGrob(lab=c("Some Text","Some More Text"),y=c(.95,.8), gp=gpar(cex=c(1.2,1.0))) ) There is too much space between the title text and the plot. I assume

Hi All, I'm trying to add a map on the following lattice plot, but not correctly... can anyone help please...
