g.data version 1.6, upgrade in response to changes in R-2.1.0
Version 1.6 of the "g.data" package is available on CRAN.
The "g.data" package is used to create and maintain delayed-data
packages (DDP's). Data stored in a DDP are available on demand, but do
not take up memory until requested. You attach a DDP with
g.data.attach(), then read from it and assign to it in a manner similar
to S-Plus, except that you must run g.data.save() to

New package: g.data
A new package "g.data" is available on CRAN, to create and maintain databases

Error: STRING_ELT() can only be applied to a 'character vector', not a 'builtin'
I have a daily job that attaches hundreds of pseudo-packages containing
data as promise objects (DDP's, ref: g.data package), and plots the
results to a multi-page pdf device. Sometimes it fails. Under R-2.2.1
it just gave segfaults. Under R-2.3.1 it gave this error message:
*** caught segfault ***

Minimal DESCRIPTION file
My "g.data" contributed package fails under R-devel. g.data creates minimal
packages which consist only of a "DESCRIPTION" file and the "R" and "data"
subdirectories, but .find.package() now rejects them because the DESCRIPTION
file lacks a "Version" field. I will fix g.data to add a "Version" field.
My question is, what else is

Bug in "[<-.matrix"? (Was: Feature Request: "matrix[1:10,1:10, block=F] <- 1:10")
Thanks to David Meyer [david.meyer@ci.tuwien.ac.at] and David Brahm
[brahm@alum.mit.edu] who suggested:
m[ cbind(index.i, index.j) ] <- vals
This works fine for the example I gave.
Unfortunately, this approach doesn't extend to using the row and column
names to make assignments:
> m <- matrix("",ncol=3,nrow=3)
> dimnames(m) <-

Is r-announce alive?
I sent a message to <r-announce at stat.math.ethz.ch> last Thursday ("New package:
colSums"), and still haven't seen it echoed on r-help or on the web archive (in
fact there is no r-announce web archive for 2002). Is something broken? Did I
need to use <r-announce at lists.R-project.org> instead?

Subsetted 1-D arrays (PR#4110)
In R-patched_2003-10-20, subsetted 1-D arrays no longer get converted to
vectors. The NEWS file documents this change, as an indirect result of bug
report 4110. I just wanted to mention this can break code in some rather
obscure ways, such as this toy example:
R> x <- sort(tapply(1:8, rep(1:4,2), sum)) # Was vector, now is 1D array
R> y <- matrix(1:4, 1,4) #

sudoku
Any doubts about R's big-league status should be put to rest, now that
we have a
Sudoku Puzzle Solver. Take that, SAS! See package "sudoku" on CRAN.
The package could really use a puzzle generator -- contributors are
welcome!

as.character.factor when the factor contains "NA"
as.character.factor contains this line (where cx=levels(x)[x]):
if ("NA" %in% levels(x)) cx[is.na(x)] <- "<NA>"
Is it possible that this is no longer the desired behavior? These
two results don't seem very consistent:
> as.character(as.factor(c("AB", "CD", NA)))
[1] "AB" "CD" NA
> is.na(.Last.value)[3]

Graphics: calling par(mar) after frame()
The following code produces 6 plots on a page, but the first is
distorted and different from the others:
par(mfrow=c(3,2), las=2)
for (i in 1:6) {
frame()
par(mar=c(7, 7, 1, 1))
axis(2); box(); abline(h=seq(0,1,.5), col=2:4)
}
The first plot's axes are mis-aligned with the plotting area implied
by the box. It seems to be a result of calling par(mar) after frame().
Is this expected

Daylight Savings Time unknown in R-2.2.1
Under R-2.2.1, a POSIXlt date created with "strptime" has an unknown
Daylight Savings Time flag:
> strptime(20051208, "%Y%m%d")$isdst

This is true on both Linux (details below) and Windows. It did not
occur under R-2.1.0. Any ideas? TIA!

rowsum() may return a vector instead of a matrix (PR#3737)
If all rows are in the same "group", rowsum() returns a vector instead of a
(1xN) matrix, contrary to documentation:
R> print(z <- rowsum(matrix(1:12, 3,4), rep("x",3)))
[1] 6 15 24 33
R> dim(z)
NULL
It worked correctly in version 1.4.0 but was broken by version 1.6.1. I'm
currently using 1.7.1 under Solaris 2.8.

outer(-x, x, pmin) cannot allocate
R> x <- 0. + 1:8000
R> y <- outer(-x, x, pmin)
Error: cannot allocate vector of size 1000000 Kb
Why does R need to allocate a gigabyte to create an 8000 x 8000 matrix?
It doesn't have any trouble with outer(-x, x, "+"). Thanks.

Floating point imprecision in sum() under R-2.3.1?
After upgrading to R-2.3.1 on Linux Redhat, I was suprised by this:
R> x <- c(721.077, 592.291, 372.208, 381.182)
R> sum(x) - 2066.758
[1] 4.547474e-13
Now I understand that floating point arithmetic is not precise, but
1) the result is exactly 0 in R-2.2.1 (patched) on the same machine,
2) .Machine$double.eps = 2.2e-16, so the error seems quite large.
Also note I get the same

v1.4.x ready yet?
Hi All,
Eagerly waiting for v1.4.x to mature a bit before getting serious about it.
Is it ready for production yet? If that's too general, where is it in terms
of stability compared to where 1.2.x is now. Anyone running it successfully
in production environment and if so what sort of config do you have?

Subversion server: v1.4 (centos) vs. v1.6 (rpmforge)
Hi,
I'm planning to upgrade an old public/internal development
infrastructure and will use CentOS 5.4 x86_64 as basis.
One of the critical server is Subversion (as an Apache httpd module).
We currently use Subversion v1.4 on the server and v1.6 on our clients.
While I was very happy with the v1.4 server over the years, we now
sometimes have weird issues which seem related to compatibility
