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) {...

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 list/forum for this questions. Thanks /Jose [[alt...

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 feedback on the accuracy of the simulations of co...

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

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)

(but not AER). Since then example('AER') throws a warning: no help found for ?AER?. I've removed and reinstalled R 4.0: it didn't help. I've downgraded to R 3.6: it didn't help. I've tried both answering yes or No when asked to install the packages in a personal lib...

...e(). The Tcl/Tk-based GUI features a broad range of different palettes from and lets the user interactively modify the underlying parameters (hue, chroma, luminance, ...) to produce new palettes. It allows for easy exploration of the effects of color blindness (through Thomas Lumley's "dichromat" package) and of desaturation (emulating a grayscale printout for example). The GUI contains various types of graphics (maps, heatmaps, barplots, line and scatterplots, ...) that can be checked to see how a chosen palette looks in practice. Most of the coding for the new GUI was done by n...

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

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

Dear r-helpers, I wonder whether, given the "#rrggbb" representation of a colour, there is a simple way to select the complementary colour, also expressed as a "#rrggbb" string. Any suggestions would be appreciated. John -------------------------------- John Fox, Professor Department of Sociology McMaster University Hamilton, Ontario Canada L8S 4M4 905-525-9140x23604
