similar to: palettes for the color-blind

Hi All, I'm having trouble with the colors on my screen getting translated to the colors in the outputted .pdf document. Here is a caricature of my problem: par(mfrow=c(1,1)) x1 = rnorm(1000) x2 = rnorm(1000)+10 y1 = rnorm(1000)+10 y2 = rnorm(1000)+10 palette(rainbow(6)) plot(x=x1,y=y1,col=y1,xlim=c(-10,20)) palette(heat.colors(6)) points(x=x2,y=y2,col=y2) dev.copy2pdf(file =

After trying to find if there was a color picker in the FAQs and the help, I thought I would send a post here. I was overwhelmed with all the wonderful color choices R has predefined (discovered after typing in colors()) but can't figure out what they all (by name) look like. Is there a color picker or some other method to display all those colors next to the name? I think I can put together

I just managed to install Adobe Photoshop CS2 in Wine 1.1.3 and have a big problem with palletes with tools, layers, history and so on. They are disappearing behind the main window. When I resize it and bring palettes back to its place, they are disappearing again as soon as I set the last one. What can I do to make them behave like in Windows?

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 <-

Hi, I would have expected that I get always 3 colors as result which is not true: hcl.colors(3, alpha=c(0, 0.5, 1)) # 3 colors rainbow(3, alpha=c(0, 0.5, 1)) # 3 colors heat.colors(3, alpha=c(0, 0.5, 1)) # 3 colors terrain.colors(3, alpha=c(0, 0.5, 1)) # 6 colors cm.colors(3, alpha=c(0, 0.5, 1)) # 6 colors topo.colors(3, alpha=c(0, 0.5, 1)) # 9 colors R-Version and

I'm working on some heatmaps, and the person I'm working with would prefer a red-black-green color palette (red denoting gene induction and green denoting gene repression). Does such a palette exist already? If not, is there an easy way to create one? Thanks, Jake

biplot could benefit from allowing colour palettes, eg. allowing col=list(xcol= xxpal, ycol= yypal) where xxpal and yypal are palettes. For an example, see the robust pricipal components in the principal componetent section of <http://www.statlab.uni-heidelberg.de/data/olive/olive10.pdf> The required change is to replace col[1L] resp. col[2L] by col[1L]] reep. col[[2L]] for example in

Dear All, During the last few days I've been trying to get ggplot2 installed in my Mac but when installing dependencies I cannot access dichromat. Error in download.file(url, destfile, method, mode = "wb", ...) : cannot open URL 'http://cran.stat.sfu.ca/bin/macosx/leopard/contrib/2.15/dichromat_1.2-4.tgz' Any suggestions? Accept my apologies if this is not the right

Duncan, thanks for your feedback. I just received your response after sending out mine. You came to the same conclusion. Should I prepare a patch and send it to you so that you can also have a look?

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! I am new to R just 3 days in it and i apologize if my questions seem very trivial and consumed your valuable time. I am coding in perl and i stumbled upon R regarding plotting good statistical graphs. I tried the kmean clustering for a large matrix ,say > 150 * 150 . I tried the example code given in the tutorial to perform 2d plot # i ranges from 2 to 10 cl <- kmeans(x, i, 20)

Dear all, I'm generally not a big fan of GUIs, but I have just discovered one thing where a GUI would be a nice thing: creating color palettes. I'm creating an "image", for transparencies for a lecture I'm giving, so this is going to look great... :-) What I'm out for, is to make green tones and red tones, and a relatively sharp break between them. This break will

Dear All, [I'd already sent this message earlier (Apr 6) but as I had no response and I still see that it is the case in R1.5 I thought I'd try again] I recently encountered a problem (actually missed some data) because "white" is one of colours in the "default" palette and that does not show up to well on my transparent (on white background). Of course it is

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. Pls see: > install.packages("ggplot2")--- Please select a CRAN mirror for use in this session ---also installing the dependencies ¡®colorspace¡¯, ¡®stringr¡¯, ¡®RColorBrewer¡¯, ¡®dichromat¡¯, ¡®munsell¡¯, ¡®labeling¡¯, ¡®plyr¡¯,

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
