I am using R to create colour plots as bitmap files. I have created a palette of 256 colours that I want to use, but the resultant output files contain only 12 colours used in dither patterns. The result is the same whether I use bmp() or png(). How can I get the true colours that I specified instead of dither patterns? (making the driver's job easier!) I am using R 1.1.0 for Windows

Hi all, I'm trying to generate barplots from simple but long (~100000-row) data files, in which each bar will comprise two stacked 'sub-bars'. All the upper sub-bars will have the same hue, and all the lower bars will, likewise, have another uniform hue. However, I wish to specify the luminance (aka brightness) of each bar (i.e., each whole bar comprising two sub-bars) separately,

...e/. Varying the chroma and the luminance only affect the distinctions between large and small and significant and non significant. But my positive and negative residuals are both large (absolutely) and significant, meaning that they will have the same chroma and luminosity, but different hues. I guess the key here is to find two separate hue values that appear substantially different *on a grayscale printer* at the same chroma and luminance. I have read through Zeileis et al. (2007, 2008) but can't quite find the answer there. I have also tried the Friendly shading to vary the...

Hi All, I'm trying trying to draw a colour wheel (a slice of hcl space) in R. Running the code below doesn't give me what I expect - there's some oddly bright colours of the wrong hue around c(0, 0) and I see three coloured circles (a small magenta, a medium sized yellow and a large cyan). Am I doing something wrong or is there a bug in the hcl code? (Also any suggestions for

I want to get a lighter shade of a color...I have a lot of colored objects and want each one printed as a foreground against a slightly lighter background. I thought I could try something like changing the alpha channel by first converting it to rgb. But prior to trying that, I'm stuck with how to get the color after converting using col2rgb() to be interpreted again as a color, rather than

I decided against creating a new "pvideo" engine -- that just seems way too heavy-handed compared to the ~10 lines of code in disp/nv04.c to deal with the PVIDEO interrupts. Even though

Is color specification like this available in R for setting postscript colors? > hue <- c(0, seq(from = 0, by = 1/(nclass), length = nclass)) > sat <- c(0, rep(1.0, nclass)) > bri <- c(0, rep(1.0, nclass)) > zcolors <- cbind(hue, sat, bri) > ps.options (setcolor=ps.setcolor.hsb,colors=zcolors)

Hello, This is my first post on this mailing list, so bear with me... My name is Morten Ofstad and I work for Hue AS (www.hue.no), a company that makes 3D Visualization software. We are looking into using LLVM for JIT compiling shader programs, to replace our own (slow) VM. A requirement for this is that we can compile LLVM in VS7.1, so I contacted Paolo Invernizzi to find the status of his

Hello, you might remember me from the previous problem with X :) I found out what I did wrong, I had installed from a CVS, but not usign the install script, which helped out alot with the config file. this time however, when I ran zmud.exe , it complained that the directory, /windows/Fonts . diddnt exist (which it doesnt), So I created the directory, to see what it would do, and then it just

Dear All, In a package, I want to use PCA function. The structure I used follow this page: http://www.statmethods.net/advstats/factor.html. fit<-principle(mydata, nfactors=9, rotation=TRUE) or: result<-PCA(mydata) But I don't known why R language in my computer noticed: "not found principle", "not found PCA". I download and installed

Hi- I am trying to plot a matrix of categorical values across time using color to represent each individual factor. For example: 1982 1983 1984 1985 1986 1987 1 19 19 68 68 19 19 68 2 68 68 19 19 68 68 19 3 26 26 34 34 26 26 26 4 57 34 57 57 34 57 34 5 34 57 26 26 57 34 57 6 28 28 28 28 28 58

Hi has anyone coded up domain colouring for visualizing complex analytic functions (such as elliptic functions)?

I''m using the ruby gem "Color" and I''m having some troubles with to_hex. I''ve installed the gem, and when I try and run the test program I get this error: >> red = Color.new(''ff0000'') => #<Color:0x3685990 @saturation=1.0, @hue=0.0, @lightness=0.5> >> yellow = Color.new(''ffff00'') =>

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 I have a palette vector of colour blind colours (in hexadecimal) which I?m using for plots, but they are not see-through, and as I wanted to overlay some histograms I wanted to convert these colours to rgb, when you can set the opacity. I have found the function col2rgb(), which works in the sense that it gives a vector of numbers but these don?t work directly in rgb because they are too

We could also do the "cvs admin -kb" thing on all the project files so that cvs won't do keyword expansion or line ending conversion. Thoughts? Reid.
