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.

Dear listers, After activating the name space for my bioconductor package (prada) I successfully ran R CMD check. However when loading the package in R and running the examples the imported function brewer.pal from package RColorBrewer is not found. I can directly call brewer.pal from the RColorBrewer name space typing RColorBrewer::brewer.pal, but it is not imported into my prada name space. When

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 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

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

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

RColorBrewer 0.1-1 is available on CRAN. The packages provides palettes for drawing nice maps shaded according to a variable as an R function. The palettes have been designed by and are copyrighted by the ColorBrewer project.

Hello R-folks, I don't get the color of the legend in a lattice-plot right. I select a palette from RColorBrewer and use it in the barchart plot. The resulting graph shows the new palette in the graph, but in the legend rectangles the standard palette is used. Adding a col argument into auto.key uses the new palette with the legend text, but not in the rectangle fill. What am I missing?

Hi, I have been trying to plot density plots using the example on: http://addictedtor.free.fr/graphiques/graphcode.php?graph=139 I used to use this function, but I cannot get any old code or even the example to work. library("geneplotter") require("RColorBrewer") x1 <- matrix(rnorm(1e4), ncol=2) x2 <- matrix(rnorm(1e4, mean=3, sd=1.5), ncol=2) x <-

Hi, I would like to do coloring of map regions based on the region values "weight". The approach I am taking is first to break regions into equal intervals, classIntervals(spdf$weight,4)$brks #4 intervals in this case and coloring all regions within the interval with the same color col = brewer.pal(4,"RdYlGn")) The max "weight" is as well the boundary of the

I thought one nice addition to a splom figure would be to have the scatterplots in the upper triangle and a color-coordinated correlation matrix on the bottom. So I tried my hand at customizing panel.pairs(), and was rebuffed. Many times. Four hours of fruitless debugging later, I turn to you for help: panel.pairs(z=teststatfull[,6:12], pscales=0, panel.subscripts=FALSE, subscripts=,

Hola, Lo hice de la forma en que propones y no me sale, no sé si algo esté mal con R, porque no me respeta ni el ?key.space?, me lo sigue poniendo en la parte izquierda del gráfico Saludos El 06/05/2014, a las 02:21, Olivier Nuñez <onunez en unex.es> escribió: > El segundo argumento en spplot ha de definir el número/nombre del intervalo al que > pertenece el area a pintar. >

Hallo all I realise this might be a "too much to ask" question, but can I improve the Lattice plot produced by the following code? The type of figure I would like to produce in each segment of the plot appears below the code. library(reserving) # http://toolkit.pbwiki.com/RToolkit <http://toolkit.pbwiki.com/RToolkit> data(GenIns) GenInsInc <- incrementalTriangle(GenIns)

I am developing a package that imports some functions from another package. The imported package (qcc) does not have a namespace and this is causing problems with loading of my package, which has a namespace. Is there a workaround to allow loading the namespace-less package? I searched the archives and found a suggestion that the package should be included in the Depends list, but this has not

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
