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.
Thanks,
Roger
