Hi everyone, I am trying to install colorspace (needed as part of my favourite ggplot2) on R v 2.7.0 running under ubuntu 7.04. The package is provided as source files and the compilation fails as below. I suspect this might be a problem with gcc v3/v4 incompatibility (or anything else), but I don't really know how to resolve it. Any advic...

Greetings, After pouring over the documentation for the 'colorspace' package, I have not been able to figure out how the plot() method converts colorspace coordinates to RGB values for display on the screen. I am convert between colorspaces with the various as() methods... but cannot seem to find a way to extract RGB (i.e. for displaying on a computer scre...

....x First thing I moved the win-library from 2.12 to 2.14 and executed a update.packages(ask='graphics',checkBuilt=TRUE) (Swiss mirror). This aborts with the console message: Error in if (any(diff)) { : missing value where TRUE/FALSE needed And the antivirus (AVG) pops up complaining that colorspace.dll contains the virus Win32/Heur I cannot ignore the thread because update.packages has already crashed when I can reach the antivirus dialogbox to push the "ignore" button. To continue I had to remove the colorspace and ggplot2 packages. Is it a known problem? What else can I do (ex...

Hi all, is there a way to automatically convert uploaded images to an RGB colorspace? I have a small intranet app, in which people can upload images. Sometimes a large 300dpi CMYK image intended for print sneaks in and causes trouble... Many thanks in advance, Nicky

I'd like to hear other opinions on that. thanks tom -------------- next part -------------- Color Management Spec ----------------------- Overview: Each window can have a color profile attached. This profile is used by the compositing manager to perform automatic colorspace tranformations. _NET_COLOR_PROFILE window property This property specifies the profile. The only type currently supported is 'ICC', it specifies that the data is an ICC profile. Other profile types may be added at a later time. Profiles are inherited from the parent window. Ap...

...'ve reproduced Ross Ihaka's notes on color, on my personal website: https://sites.google.com/site/spurdlea/exts/ihaka_r_stats_787_10_color.pdf (This has been reproduced with permission). Another good article is: https://www.r-project.org/conferences/DSC-2003/Proceedings/Ihaka.pdf And the colorspace package vignette is also a good resource: https://cran.r-project.org/web/packages/colorspace/vignettes/hcl-colors.pdf These are good resources for people interested in mathematical or statistical graphics.
