Given that if you specify the 'nchars' argument you are trying to do
something unnatural, I don't see why you find it incorrect to get warnings
about mismatches between what you supply and what you asked for, but
expect one if what you supply matches what you asked for (and truncation
occurs).
I have recently been using writeChar and writeBin to write binary
files. These functions makes it very easy to write OS-independent
files, which I am very happy with.
I have however found a few issues, best illustrated by a short example
> con <- file("test", open = "wb")
> writeChar(as.cha
Hi all,
The write_PACKAGES function has a 'fields' argument that allows a user
generating a PACKAGES file to specify additional fields to include.
For symmetry, it would be nice for the available.packages function to
be able to read those extra fields when specified.
Similarly, it would be useful
Hi,
I guess the question often comes down to whether it is a bug report,
or a question. If you know it is a bug, and have a complete and correct
example where the obviously incorrect behavior occurs and you are
positive that the problem is the package then sending it to the
maintainer is app
If users post a bug or problem issue to an R-based news group
(R-devel, R-help, BioC - though BioC is far more forgiving)
they get yelled at for not reading the posting guide
and FAQ.
"Please *_do_* read the FAQ, the posting guide, ..."
the yellers do say. So I read the BioC FAQ and it says...

I don't think you owe anyone any explanations or descriptions of
yourself. The only thing you really need to provide is a good description
of any problem you post as discussed on the r-help posting
guide and as discussed in the single line at the bottom of every
r-help message.

I have one question
Have a look at Rfind.bat in
http://cran.r-project.org/contrib/extra/batchfiles/
which uses the registry to find various software used by R.

Hi:
Russ Moffit of our Honolulu Lab has made a modification to the R
netcdf package 'ncdf' so that it can access remote netcdf files
using OPenDAP (http://www.opendap.org). The package works on Linux,
and with help from Don MacQueen was also ported to Macintosh OS X.
We have had a lot of dem
Gabor, Roger,
thanks a lot for your immediate answers.
Knowing that this is subject to change means a lot less coding for me :-)
Good news ... for me, and first of all for the impressing S4 system.
Thanks again

I think having the correct TeX path is the user's responsibility, and

I think you're right---this shouldn't happen in theory, but it does because of
the internal representation of S4 objects in R.
In R devel (to be 2.4.0), this changes and I believe your example will no

Hello.

Don't worry if you have a deja vu, it's from the help page.
Your new class is said to have a fixed structure: two slots, x, and y,
and that should apply to all objects you construct as mem

Dear all,
The existing R packages for doing power analyses (pwr, hpower) seem
quite basic/limited, compared to the power analyses implemented in the
UnifyPow SAS module.
I wondered if there are people working on power analyses for a broader
range of statistical tests than pwr and hpower cover
