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

Anyone who is interested in using optimal colour palettes should look at the work of Cindy Brewer: www.colorbrewer.org I have written code to use her colour schemes in R. It is included below. Perhaps someone may find this interesting enough to work into a package. Included also is a function showpalette, which was posted here a while back. I don't remember who wrote it. I have copied all

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.

I have seen a couple of posts about color schemes like those at the ColorBrewer site. Most recently: http://geography.uoregon.edu/datagraphics/color_scales.htm These color schemes can work very well for regions (bars, polygons, images, etc.) but are not very suitable for points and/or lines. Is anyone aware of research/suggestions for a color scheme to use for scatter plots? I've looked at

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

Hello I'm using rainbow function to generate 10 colors for the plot and it is difficult to tell the neighboring colors from each other. How can I make the colors more differently. Thanks Zhaoming [[alternative HTML version deleted]]

Hola! I thought that one main purpose of the INDEX file as shown by library(help = ...) was to give further pointers to use to search for help. But some pacakges have items in the index file with NONE help page, and further, non items in the index with help page. As an example I use > library(RColorBrewer) > library(help=RColorBrewer) # but this is not about RColorBrewer in particular,

Hi, I am plotting a policy function (result from a dynamic stochastic optimization problem, discretized approximation). The policy function maps from an 2 x 2 x 2 x 3 x B x F state space to a B x F state space (B and F are usually between 4-6, and represent domestic and foreign savings. The other variables are income (Y), inflation (Pi), domestic and foreign interest rates (R and Z)). I

Hello, R friends,   I'm trying to change colors of my horizontal bars so that they show a sequence. I chose the ColorBrewer palette "Blues". However the resulting plot doesn't show any changes to the default. I tried several places of "+ scale_colour_brewer(type="seq", pal = "Blues")" with no effect. This is my code:   p <- ggplot(data, aes(x =

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

Dear List, I am new to lattice plots, and am having problems with getting my plot to do what I want. Specifically: 1. I would like the legend to have the same symbols as the plot. I tried simpleKey but can't seem to get it to work with autoKey. Right now my plot has dots (pch=19) and my legend shows circles. 2. I have nine groups but xyplot seems to only be using seven colors, so two

I will second Roger's suggestion, colorRampPalette is a great function for creating your own palettes. For example, Matlab's jet palette (also available in fields package under peculiar name 'tim.colors') can be defined by: jet.colors = colorRampPalette(c("#00007F", "blue", "#007FFF", "cyan", "#7FFF7F", "yellow",

Hi everybody, I am wondering how i can add a "stretch" color bar / legend to a graph that uses colorBrewer to define the colors in it. I will try to explain my graph, but i also uploaded it at: ftp://ftpext.usgs.gov/pub/er/fl/st.petersburg/Monica_pal/ The file is: robcor_training_pca.pdf - i will also attach this file in case some people accept attachments. So i took apart the

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

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]]

Dear Erich and John, thankyou for providing RColorBrewer! Are you working on options for CMYK or RGB return values? Thanks again, Darren [[alternative HTML version deleted]]

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

Hallo, I just installed all needed packages for my project on my PC. But I cannot load all at one time. I now want to load limma. How can I realize the following plan: I want to install for example limma inclusive all needed other sub packages (add-on). Can anyone tell me the corresponding command? Thanks, Corinna Here is the result of the command library(): Pakete in Library

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
