I think the answer to this should be known/discussed more widely:
Jim, you are right:
The patch to seq(.) should have made it to R-help.
[[actually in the mean time, the issue was raised that my patch
was much more than was needed for dealing with rounding errors
in the seq(.,., by= ) case
]].
Note that there *are* other known bugs, all(?) of which being
of much more low-level (and ``deeper'') nature.
Things like
mode(NULL) -> "list"
[now (in 0.63 "unstable") corrected to "NULL"].
For bug submitting & tracking,
Peter Dalgaard has recently setup a web place
[and 0.63-unstable has function bug.report()]
were bug can be reported ``discussed'', etc. :
http://R-bugs.biostat.ku.dk/R
It is also available from CRAN's main page
---
There are also plans to regularly post a list of these bugs to R-devel (not
R-help!).
If we know of a bug that affects high-level functions in bad way,
we usually *do* post to R-help....
R-devel is also for people who develop considerable amount of own R
functions. There are things on R-devel which are not of interest to all
of the subscribers, but I think CRAN contributors like you should be part!
