Dear all,
From the writing extensions manual:
Other dependencies (external to the R system) should be listed in the
‘SystemRequirements’ field, possibly amplified in a separate README file.
I guess one problem is the user may not realize that the -dev version is
needed, and just sees libxml2
To me it seems like writeBin() writes one char/byte more than expected.
con - file(testbin, wb)
writeBin(ttccggaa, con)
close(con)
con - file(testbin, rb)
readBin(con, what=character)
[1] ttccggaa
seek(con, what=NA)
[1] 9
close(con)
con - file(testbin, rb)
readBin(con, what=raw, n=20)
from ?seek
‘seek’ returns the current position (before any move), as a
(numeric) byte offset from the origin, if relevant, or ‘0’ if not.
Your string is nul terminated (9 bytes long). That would be the
current offset. If you only read one byte, you'd have to be more than
0 bytes offset.

You want writeChar rather than writeBin to avoid the null termination of
strings.

Thanks for the report. I'll take a look.
I'm now past one major time sink, and will have some time to catch up on
old problems; I'll add this to that list.

Been too fast : I am in Central European Time (GMT +1), which explains
the time conversion. Still, I find it highly annoying that as.POSIXlt
assumes that the time is given in GMT and has to be converted to
whatever timezone you're in if you don't specify anything.
Probably this behaviour is not

Much of TZ-hell (I almost dare say all) has been sorted through in xts.

Peruse the sources for inspiration or just take some comfort in that
you are not the only one ;-)

This is not specifically a bug, but an (implicitly/obscurely)
documented behavior of read.csv (or read.table with fill=TRUE) that can
be quite dangerous/confusing for users. I would love to hear some
discussion from other users and/or R-core about this ... As always, I

Take a look at all.vars to start with That will return the vars as

This is probably the same underlying bug, but it is not caused by
semicolons.
If you use keep,soure=TRUE with expand=FALSE and interpolate a code
chunk, the name of the chunkl is sent to the TeX file once for every
line in the chunk. Specifically, the source file:
%%%

Hello, All:
How can I obtain the location of an example data file in a
package during R CMD check?
I want to include sample raw data files in a package and have
them read by a function in the package. It occurs to me to put such a
file in \inst\rawdata and have examples find
Hi Spencer,
I think one of the early phases of R CMD check is R CMD install - it
installs the package into a special location so that it doesn't
override existing installed packages, but still allows function to
work exactly as if they were in an installed package.
