Hi, I've been doing a lot of CA modeling lately and am now wanting to make some checkerboard plots in R. Let's say I have a matrix: > is.matrix(junk) [1] TRUE > junk [,1] [,2] [,3] [,4] [,5] [1,] 0 0 1 0 0 [2,] 0 1 1 1 0 [3,] 0 1 0 0 1 [4,] 0 1 1 1 1 [5,] 0 1 0 0 0 > and I want to make a checker...

...hat was version 8.5. Now, two versions after (yes, I've overslept a whole release, and I feel fascinatingly relaxed after that), the problem persists. Running WINE in fullscreen results in display corruption, symbolically called "Checekerboard of Doom", because, well, it looks like a checkerboard. Anyone around here have an idea what to do about it? (apart from not using full-screen)

Hi All, is there a reasonably simple way of using a black and white chequer/checker board pattern as a colour: barplot(mydata, col = c('red', 'blue' 'checkerboard')) ? BW F -- Federico C. F.

Hi R Helpers, I'm still new to R and i experience many difficulties..I'm using vegan package (R version 2.11) trying to calculate checkerboard units for each species pair of a matrix. I've prepared the function: pair.checker=function (dataset) {designdist (dataset, method="c("(A-J)x(B-J)", terms ="binary", abcd=FALSE)} to use with function oecosimu as follows: oecosimu(dataset, pair.checker, "tswap&quo...

I am working on dumping raster data from R into PNG files using rasterImage(). I am working with a test matrix from the rasterImage() example and using it to produce a PNG image with the following code: # From the example for rasterImage(). A 3 pixel by 5 pixel b/w checkerboard. testImage <- as.raster(0:1, nrow=3, ncol=5) testImage [,1] [,2] [,3] [,4] [,5] [1,] "#000000" "#FFFFFF" "#000000" "#FFFFFF" "#000000" [2,] "#FFFFFF" "#000000" "#FFFFFF" "#000000&q...

Hi Everyone, Does anyone know how to take the output of a 2D fft() and shift the DC component to the center? Is there a function that does that? if you know, please send me an email. thanks for any help! brad __________________________________________________ . http://im.yahoo.com -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hey Y'll, Where might I enter a complaint about the new tabs showing a tile of recent web sites visited. I don't like that. I would like to change that setting but I don't see anything in the preferences to adjust. -- _ ?v? /(_)\ ^ ^ Mark LaPierre Registered Linux user No #267004 https://linuxcounter.net/ ****

Thanks - I suspected it was too new. I'm finding the monitor capabilities miss identified even if I use an older card - I'm
