Dear All, I'm trying to track down a problem with my quantreg package reported by a user doing censored quantile regression. When he runs the test4.R file attached below (which reads the csv file also attached) on his windows machine he gets an error like this:
> Error in dimnames(B) <- list(c("tau", dimnames(x)[[2]], "Qhat"), NULL) : > length of 'dimnames' [1] not equal to array extent > In addition: Warning message: > In rbind(grid[1:J], B, qhat) : > number of columns of result is not a multiple of vector length (arg 2) However, when I run the same thing on my mac there is no error, no warning. And -- more strangely-- running this on another windows laptop here in Urbana also encounters no problems. I thought that this might just be a seed problem since there is a bootstrapping step at the end, but the original user has tried several seeds and always gets this error. We are all running 2.15.1 and V4.94 of quantreg. I understand that YMMV, especially on windows, but it is difficult to debug this sort of thing when I can't reproduce it. Any suggestions or other experience would be welcome. The test problem takes a minute or so to run on my mac.
