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, Ontari...

...col2rgb(5) # the integer value of the first level # and this is res[,1] which by the way is palette()[5], aka "cyan" ?col2rgb says: col vector of any of the three kinds of R color specifications, i.e., either a color name (as listed by colors()), a hexadecimal string of the form "#rrggbb" or "#rrggbbaa" (see rgb), or a positive integer i meaning palette()[i]. Non-numeric values are coerced to character. So in the example the factor is being taken as its integer representation, and finding an integer as the input value, col2rgb goes to palette(). Perhaps this is a n...

Dear List, I have a 47 species * 83 samples matrix containing percentage abundance data. I have two cluster analyses one of the samples and one of the species, and have ordered the rows and columns of the species by samples matrix according to these two cluster analyses. So far so good! Now what I want to do is create a plot with the species dendrogram at the top of the plot, the samples

I have a simple bar chart with annual precipitation (jan to dez). I want to plot, above each bar (on a line), a square wich is color based on a scale (0-100%). With 0 being white and 100 black, like a gradient. Is it possible? How to? Thanks -- Fernando Andreacci [[alternative HTML version deleted]]

Dear, I am having a lucky day. I am programming in RStudio and when I type "black" (quotation signs included, the word turn into a word with black ground. Couldn't get rid of the background----copying to Word, Excel, text editor and paste back to Rstudio, the word is still in black background? Help! ??? dv.group<-c("black","othrrace");

hi all, i have a simple scatter plot, and i'd like to make it so the scatter plot colors are slightly transparent. i see in a previous post that someone mentioned the "alpha" parameter, but i am not sure how it can be used with the 'plot' function [*]. for example, suppose i have: plot(mydata$column1, mydata$column2, col="red", cex=1) i now want to make it so

Hello, I would like to make a plot (preferably lines, but points will do too), where the line segment changes color depending on the value of the y-axis. For example, let's suppose the y-axis range is from -1 to 1. Points close to -1 would be colored blue, while points close to 1 will be colored red. Points in between will be varying degrees of blue/red depending on how close they
