When attempting to install the ?colorspace? package on RedHat Linux I get the following error. Any help would be appreciated.

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

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

Hi, The move to sRGB is nice, is there any interest in adding an interface to lcms, http://www.littlecms.com, to allow gamut matching? I can think of a lot of instances where I would like to render a figure as it would appear on my printer. This is probably best done as a separate package though, at least at first.

On OS X 10.8.2, after I installed ggplot2, and picked mirror of Singapore. it could not find qplot function. Could anyone pls help me ? Thank you.

The following R code causes R to crashes under recent r-devel builds of R: library(ggplot2) RCBD.lay <- data.frame(Blocks = factor(rep(1:5, each = 6)), Units = factor(rep(1:6, times = 5)), Treatments = factor(rep(1:6, times = 5))) ggplot(data = RCBD.lay, aes(x = Units, y = Blocks, label = Treatments)) + geom_text(aes(colour = Treatments)) I

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).

This is an update (version 1.2), not a new package, but given recent postings on the R lists an announcement may be helpful. The 'dichromat' package has color schemes designed for people with red-green deficient or anomalous vision, tools for simulating the effect of color blindness, and tools for creating color ramps and palettes (these last will be in R 2.1.0). I would welcome

Everyone, I'm working with scatter plots with different colored symbols (via lattice). I'm currently using these colors for points and lines: col1 <- c(rgb(1, 0, 0), rgb(0, 0, 1), rgb(0, 1, 0), rgb(0.55482458, 0.40350876, 0.04166666), rgb(0, 0, 0)) plot(seq(along = col1), pch = 16, col = col1, cex = 1.5) I'm also using these with transparency (alpha

Currently i''m uploading files and i have a file chooser.. <%= file_field(''upload'', ''filename'') %> Is it possible when the file chooser comes up to filter by image type?

Dear list, The dichromat package defines a dichromat function which "Collapses red-green color distinctions to approximate the effect of the two common forms of red-green colour blindness, protanopia and deuteranopia." library(dichromat) library(grid) colorStrip <- function (colors = 1:3, draw = TRUE) { x <- seq(0, 1 - 1/length(colors), length = length(colors)) y <-

i have a data frame with 2 columns of dates. with str(dataframe) i have ensured myself that they were indeed formatted as dates. one column has NA's in it. the aim is now to make a third column that chooses date1 if it is a date, and choose date2 if it is a NA. i am trying df$date3=ifelse(is.na(df$date1), df$date2, df$date1). this leads to unexpected behaviour: the resulting column is

Dear R-help, Can anyone tell me if it's possible to call up the "directory chooser" (the one you get when you click on "File" -> "Change Dir...") in Rgui from the R command line? Seems like file.choose() can't be used to choose a directory. This is in R-1.8.1 on WinXPPro. Any help much appreciated! Andy
