...rocess the grey and rgb attributes as in the code in the above page. Would appreciate it if I could get some explicit help on processing the image matrix. I don't follow in detail how a square portion of the graphic is extracted also. 2. Instead of a cube, I am interested in mapping images on a cuboid (l!=b!=h). Could I get tips on how this can be done. How should the dimensions of the image matrix be tailored then? 3. The following line in the code appears to identify and fix the corner points : coords <- rbind(  c(0 , 2, 3),  c(1 , 3, 2),  c(3, 0 , 2),  c(2, 1 , 3),  c(2, 3, 0 ),  c(3, 2,...

Hello All, I have a dataset and I wish to obtain all possible data cuboids from it using R . For eg if my data frame is : A B C 1 1 1 1 2 1 2 2 1 The output intended is : A=1 A=2 B=1 B=2 C=1 A=1,B=1 A=1,B=2 A=2,B=2 A=1,C=1 A=2,C=1 B=1,C=1 B=2,C=1 A=1,B=1,C=1 A=1,B=2,C=1 A=2,B=2,C=1 Are there any function(s) to do this in R ? I tried a combinat...

Hi the list, I would like to draw some lines with misc3d. I find a lot of tools to draw surfaces, but nothing for simple line... Is it possible? Note that I know that it is possible to draw lines with rgl (using lines3d), but I need to do it with misc3d to export the drawing in .asy format. Any solution? Christophe
