hi, all I am looking at R package RGL to draw a colored mesh/surface plot like this one (from matlab). http://www.mathworks.com/access/helpdesk/help/techdoc/visualize/cbar.gif The key features I am looking for is surfaced with grid and color, but not the terrain-like gradient. but I didn't come even close to it after browsing through rgl help file. have anyone drawn something like this

Hi, for those with experience of Gruff module: suppose I want to send image from server straight to the browser (as example on gruff web site): send_data(g.to_blob, :disposition => ''inline'', :type => ''image/png'', :filename => "gruff.png") the server seems sending this binary data ok, but I am having

hi, all I have two questions on using R console effectively (this is on Mac, not sure if it applies to win platform): First, I'd like to make the console font bigger, the default is too small for my screen. There is a "Show Fonts" from Format menu where you can adjust it, but it seems only for current session. Next time I start R, I have to redo everything. My question is, is there

hi, all I inherited a data set with format like the following: para.A para.B para.C observation.1 observation.2 observation.3 .... Essentially, the same experiment (with same parameters) are conducted 3 times, with corresponding observations. What are the efficient ways of re-arranging this data set in a one row per observation such that: para.A para.B para.C observation.1 para.A

Hi, Figure 13 of Emmanuel Paradis's "R for Beginners" was produced by termplot working on an aov object. The lower right-hand plot is labelled "Cook's distance plot", and I'd really like to produce a similar type of figure, but in a totally different context. (I'm not even sure what this kind of figure is called, perhaps an "impulse plot", where

I am interested to take a course in R. Someone know of some course in europe for the first semester of the next year?. Happy Year Thank you, Xavier [[alternative HTML version deleted]]

Would this work in general? Say I have a document with figures, special equations, text, and tables. The text and tables are relatively easy. The figures would need a conversion from pixels to lines, and the equations maybe printed out, counted as a figure, and then added to the line count. It would also be tricky if a title line was at 32 point font and the text at 12, and the more complex the

Robin Hankin's post reminded me to post about the following recent addition to 'Writing R Extensions', in the section on 'Submitting a package to CRAN' Ensure that the package sources are not unnecessarily large. ... As a general rule, doc directories should not exceed 5Mb, and where data directories need to be 10Mb or more, consideration should be given to a

It's still not entirely clear to me what framework you're using to generate the PDF, but if it's rmarkdown/Rnw (Sweave)/Quarto-based, then as far as I know all of those frameworks use LaTeX as the last step in the script-to-PDF pipeline, and allow the inclusion of arbitrary LaTeX code, so the 'lastpage' package would do this for you:

hi, I am a R beginner. One thing I notice is that when do graphing is, if I want to draw two figures in a row such as this: par(mfrow(1, 2)) plot(...) plot(...) Each figure inside will be rectangle instead of the familiar square shape. Though you can drag the edge the window to resize it. I would have prefer this can be done automatically ... also when I do the pdf export for example. Is this

He clearly stated he was using the pdf() graphics device.

Latex and R are really cool stuff. I am just wondering how they are used in industry. But based on my own experience, very rare. Why? How about the opinion of other listers? Thanks.

I am using lattice to make figures as pdfs: trellis.device(device = "pdf",file = "Figure6.pdf",color = FALSE) I need to specify some blank space on the left-hand margins (the pages will be bound so we need about 0.5 inch)). I have tried a number of solutions but none seems to work (e.g. par.set). Can this be done when initiating the plotting device? Or is the some other way

R has had the ability to generate pdfs with transparent colors for a couple of years now using pdf(..., version="1.4"). By default, Sweave uses just 'pdf' (without version 1.4), so a hack is needed when using Sweave to create pdfs with transparent colors. See http://tolstoy.newcastle.edu.au/R/help/04/11/6655.html I would find my work process simpler if R defaulted to

Hi R-ers, I'm wondering if anyone has investigated a method for embedding audio files in R graphs (pdf format), and allowing their playback to be triggered interactively (by clicking on a graph element for instance). I know how to do this in latex pdfs with the multimedia package, but it seems that R would provide a more appropriate platform for many reasons. Thanks for any help you

Hi everyone, I have been making a fair amount of figures in R recently that I've been touching up with Illustrator and I've found a difference between pdf and ps files and I was wondering if someone could enlighten me about them. While the figures look the same, the ps version tends to have truncated strings. The last character of short strings tends to be on a string of its own, located

One of the most fundamental characteristics of R programming is the use of data frames of column vectors, and one of the very first challenges I had as a then-Perl-programmer was coming to grips with the fact that unknown-length CSV files would be read completely into memory as rows and once the entire CSV was in memory it would be transposed into column vectors. I was resistant to this philosophy

hi all - i'm having some difficulty figuring out how to convert between "user units" (which i can't find a definition for in the plotrix package) and either (a) device units (e.g. inches with PDFs) or (b) user coordinates along any particular axis. as an example, suppose i set up a PDF device with inches, the device has both outer and inner magins, and the plot region has

Hello, in scilab /Matlab there are functions that can create linear sequences (like R's seq()) as well as logarithmic sequences. Is there a logarithmic aequivalent of seq()? Or maybe this would be an idea for newer R-releases, maybe a type-option with "linear" and "logarithmic" as parameters....?! Ciao, Oliver
