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 advice will be appreciated - or perhaps somebody has got

Dear all, I'm having problems installing the colorspace package on Red Hat Enterprise Linux 5: * Installing *source* package 'colorspace' ... ** libs gcc -std=gnu99 -I/usr/lib/R/include -I/usr/lib/R/include -I/usr/local/include -fpic -O2 -g -pipe -Wall -Wp,-D_FORTIFY_SOURCE=2 -fexceptions -fstack-protector --param=ssp-buffer-size=4 -m32 -march=i386 -mtune=generic

I have lots of data that I need to display, and I think hexbin would be good for it. However, I cannot load one of the requried packages associated with the hexbin package: > library(hexbin) Loading required package: colorspace Error in loadNamespace(package, c(which.lib.loc, lib.loc), keep.source = keep.source) : in 'colorspace' methods for export not found: [, coords, plot

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 screen) triplets from color space coordinates. Here is a sample of the data that I am working with: H V C x y Y 2.5Y 0.2 2 1.43 0.97 0.237 2.5...

I am setting up a new Ubuntu lucid system on a Dell Precision T3500, quad core, E5507, x86_64 box and am having some difficulty updating r-cran packages as per the instructions at http://cran.us.r-project.org/bin/linux/ubuntu Perhaps the instructions are incomplete or wrong, or I've misunderstood something, and/or I've run into a dependency problem among r-cran- packages, vcd in

I just upgraded my Win7 32bits installation to 2.14.0 after deinstalling 2.12.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

Hi all, When installing ggplot2 on with install.packages("ggplot2", dep = T), the colorspace dependency doesn't get installed (see below for transcript from R session). The relevant lines from my description file are: Depends: R (>= 2.4), grid, reshape (>= 0.8.0), proto, splines, MASS, RColorBrewer, colorspace Suggests: quantreg, Hmisc, mapproj, maps Have I done something

Dear useRs, we have just released a new version (1.2-0) of the "colorspace" package: http://CRAN.R-project.org/package=colorspace In addition to the infrastructure for transforming colors between different color spaces (RGB, HSV, HCL, and various others) and support for different types of color palettes (qualitative, sequential, diverging), there is now a new graphical user

Hi all, anyone has an idea how I could fix this? \donttest{ ## Set colors from colorspace package with a fallback col <- try(colorspace::rainbow_hcl(5), silent = TRUE) %||% rainbow(5) } The problem is that this makes R CMD check freak out (http://www.r-project.org/nosvn/R.check/r-devel-linux-x86_64-debian-clang/falsy-00check.html) if the colorspace package is not declared as a dependency.

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

As part of my GSoC project I have to work out a spec that covers how applications should communicate color management related properties between each other and the compositing manager. The main idea of the project is to let the compositing manager do the color management on behalf of the applications. But before that can happen, the applications have to tell the compositing manager how they want

Hi Z I think supporting HCL color spaces more, is a *very* good idea. However, I doubt many R users, understand the motivation for HCL color spaces. I'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:

I keep finding the Win32\Huer virus in colorspace_1.1-1.zip for R x64 2.14.1 running MS Windows 7. As a result I am not able to use rattle or ChemometricsWithR. I have tried several different mirrors with the same result. Fortunately AVG has caught and quarantined the problem, but the colorspace package is not available. I can use the package on my Linux OS, but, of course, Linux
