dear R experts---I am struggling with the requirements to prepare my files for my printers. I am printing in 2/2 format, which means cyan and black for me, which they take from my color-separated pdf files. R comes into play, because it produces all the figures that are embedded in my book (pdflatex). now, TeX has no problems producing CMYK files. However, R produces RGB files (for

Your text is asking something else: if those are colours, you don't want to treat each of them as a single integer. A

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

Hi all, I am trying to download the Rcolorbrewer package from Cran http://cran.r-project.org/web/packages/RColorBrewer//index.html It seems the files have been removed. Does anyone know where can I download the package? Thanks. Hannah [[alternative HTML version deleted]]

Hi, How would you calculate the "mean colour" of several colours, for example c("#FF7C00","#00BF40","#FFFF00")? Yours, Atte Tenkanen

Hi all, I have 35 years, I have been working since I exit from University. I have returned to make a phd...I´m fortunatelly I´m working so unfortunatelly I have few time to study (I have also a baby with 16 months). I´m trying to use R but sometimes it gets very difficult. I´m trying to put this code in my polygon function colramp=colorRampPalette(brewer.pal(9,"YlOrRd") to use

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

It appears that the chromatic adaptation feature of `grDevices::convertColor`is broken, and likely has been for many years.? While a little surprising, it is an obscure enough feature that there is some possibility this is actually broken, as opposed to user error on my part.? If it turns out to the latter, I apologize in advance for spamming this list. Consider: ??? rgb.in <-

I've found RColorBrewer useful for its qualitative palettes, but wished that it could generate more than 12 qualitative palettes (e.g. with Set3). Any suggestions for alternative color palette generators that can handle e.g. 18 distinctive colors? (I'm aware of using rainbow(), but this doesn't generate enough distinct colors when the number of palettes is large). Thanks, Andrew

A recent article in the earth science literature cited below and available at http://geography.uoregon.edu/datagraphics/EOS/ points out that rainbow color schemes and mixtures of green and yellow can be troublesome for people with color-deficient vision. The authors propose alternative schemes that can be viewed and downloaded in RGB, HSV, CMYK, and RGB256 formats from

I'm looking for a scheme to generate a default color palette for plotting points, lines and text (on a white or transparent background) with from 2 to say 9 colors with the following constraints: - "red" is reserved for another purpose - colors should be highly distinct - avoid light colors (like "yellow"s) In RColorBrewer, most of the schemes are designed for area fill

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.

Hi all, I had the need to create a colorbar considering the alpha channel of the colors, but colorRamp() and colorRampPalette() ignored the alpha argument in rgb(). So I performed some minor modifs. in their codes, as to support the interpolation using the alpha channel. I guess that those simple modifications might be useful for other people, so perhaps it would be worth to add them to

Hi there everyone! So I'm a student in college, taking a very basic Statistics course. We're using R for most of our assignments. I've hit a pretty big wall here. I'm attempting to create a heat map of the entire united states which corresponds to a set of percentages I have for each state. My teacher suggested that I simply create a color palette with RColorBrewer that is in the

Hi everyone, Can anyone kindly help me with the interpretation of colors in the RColorBrewer Package (brewer.pal) ? For example, in brewer.pal command, when picking up the "RdBu" palette, does red means larger or smaller value? I am new to this fantastic program, and I have searched up and down, no clue :( I will really appreciate your time if you can kindly give me a hand.

Can you reverse the color scheme order in rcolorbrewer. If so, how? [[alternative HTML version deleted]]

Please do study the FAQ and posting guide: R 2.7.0 is not the current sources, and this was changed a month ago in R-devel. You were asked to check for such changes before submitting a report. Also, there is no unique way to do undercover removal in conversion to CMYK, and so it is wrong to call any method 'wrong' -- in fact the one used in earlier versions of R was a documented

A stupid question but does anyone know how to express the actual colours used by the main Canadian political parties? I want to do a couple of ggplot2 plots and have lines or rectangles that accurately reflect the party colours. I can probably play around with RColorBrewer or something to figure it out but if some some already has got them it would save me some time especially with the NDP
