Hi! Is it possible to display a 3d array as an RGB image? For example, given the following array: > matriz3d , , 1 [,1] [,2] [,3] [,4] [,5] [1,] 170 174 173 172 161 [2,] 171 178 174 166 149 [3,] 168 174 173 166 156 [4,] 171 170 173 166 164 [5,] 167 170 170 171 169 , , 2 [,1] [,2] [,3] [,4] [,5] [1,] 138 131 128 128 125 [2,] 138 127 129 122 134

...No problems here. However back when the 2.6.0-testing (first encountered the problem in 2.6.0-testing4's initial release) series kernel were being released I could not get my mount to continue to work correctly. The problem was that it was/is being mounted under the following permissions: tstarr@host:~/mount$ ls -l total 0 drwxr-xr-x 1 501 dialout 0 Apr 7 20:39 Audio drwxrwxr-x 1 501 dialout 0 Apr 9 01:29 Desktop drwx------ 1 501 dialout 0 Apr 2 15:33 Documents drwxrwxrw- 1 501 dialout 0 Feb 19 10:38 Graphics drwxr-xr-x...

...(i.e., 1024 X 1024 x 3). I'd like to hear how this function works for people with large amounts of RAM (>1Gb). imatestrgb: function (mat3d,ngris=64,stretch=" ",ver=T) { # DISPLAYS A (m,n,3) ARRAY AS A RGB IMAGE # From an idea by Ben Bolker. In particular I DO NOT USE: # apply(tstarr/256,c(1,2),function(z)do.call("rgb",as.list(z))) # which is costly in memory and time. # IF ver=F, saves the pseudocolor image as a list # NOTE: if range(mat3d) is VERY different from |0,255|, # stretch MUST BE "l" or "n" m <- dim(mat3d)[1] n <- dim(mat3d)[...
