OK, no need to emphasize too much... sorry for my ignorance on the R help
sections. To answer Duncan Murdoch, I do not have _real_ example because the
example was provided by someone else in R-help. By the way, the example was
mispelled in my previous mail and is (under R 1.6.1 and Win 2000):
> ind <- 10 * (73.1 + (10 * seq(14)) - 76)
> ind
[1] 71 171 271 371 471 571 671 771 871 971 1071 1171 1271 1371
> as.integer(ind)
[1] 70 170 270 370 470 571 671 771 871 971 1071 1171 1271 1371
># thus:
>mat <- seq(1420)
>submat1 <- mat[ind] # NOT what I expected
>submat2 <- mat[round(ind)] # much better
I suppose that such a complicated construction of "ind" had some meanings in
the initial application.
Again, I do not complain for a bug. There is no bug. I just suggest to
mention this behavior in help files...
