Dear All, Consider a matrix (N x N) where each entry is either zero or one (can hardly get any simpler). Now, I would like to plot it as a 'chessboard' where every matrix entry is a black (1) or white (0) square. Whatever tool I use to plot it, it should not try to interpolate the data at all. I found some online references http://www.phaget4.org/R/image_matrix.html but probably I can resort to something much simpler. Can anyone provide me wi...

...things"), which cause a memory protection fault. I've a question regarding the image function, which I use frequently and for various purposes. Apparently, the S and the R version of the image function don't behave the same way. I've attached below a function that under S produces chessboard-like figures, while it produces irregular pattern with R (never mind different colours in R and S, this is not a point). Does anybody know how can one obtain the chessboard images (squares or rectangles of the same size) with R? Best regards Zivan test.image <- function(n) { if(n < 2)...

...everything appears to be happy once again. Anyhow, uh, like I said, it appears to work just fine for 300 guests and below, which is enough for me. I''m guessing that much above 300 guests (338, I believe, is the tipping point when you use my setup) we just run out of interupts. [root@chessboard ~]# xl list |wc -l 300 [root@chessboard ~]# wc -l /proc/interrupts 1830 /proc/interrupts so that all looks right to me. Now, it''d be a nice safety feature if xendomains didn''t hoark when it went over the limit, as I need that to keep the existing domains running, but it looks l...

Hola Freddy. Yo parto de un shape en que tengo los típicos archivos .shp, .sbx, .sbn, .shx y .dbf. En la tabla tengo el área de los poligonos en m2, el perímetro, el estado y el código ISO del estado dispuesto por el SGM. ¿Me puedes orientar un poco más? Gracias, Sebastían.

...ce code once, and had to be strapped down for his own (and my!) safety. It's time to rewrite it in a more object-oriented manner. I have a couple of options: port the thing to c++, or deal directly in R. The R route has a number of advantages. For example, I deal with fluxes between adjacent chessboard-square-style elements. The Fortran idiom is: do 10 i=1,200 do 20 j=1,200 flux(i,j) = ( r(i,j)*u(i+1,j) + r(i+1,j)*u(i,j) ) /2 20 continue 10 continue where r is the density and u the x-component of velocity. I might need to do this or similar-looking things such as u(i+1,...
