DierckxSpline segfault
I've just encountered a segfault when using DierckxSpline::percur

pspline <- percur(x, y)

options(chmhelp = TRUE)
Hi all,
Here's a curosity I ran into since upgrading to 1.6.2 (precompiled
for Windows). When using the chm help I get the following warning. I saw
a recent post regarding this as a new warning (``dyn.load warning
message in R1.6.2 on Windows XP'' dated 1/28/03), but not in the context
of the help system. The warning only appears once and does not prevent

distance between two matrices
Hi all,
Say I have a matrix A with dimension m x 2 and matrix B with
dimension n x 2. I would like to find the row in A that is closest to
the each row in B. Here's an example (using a loop):
set.seed(1)
A <- matrix(runif(12), 6, 2) # 6 x 2
B <- matrix(runif(6), 3, 2) # 3 x 2
m <- vector("numeric", nrow(B))

update.formula and backticked colons
I just noticed the following in update.formula and I'm wondering if
this behavior is the intention of the developers. Here's an example:
update(`a: b` ~ x, ~ . + y)
Note now that the response has no backticks and is interpreted as a:b
(i.e. ":" is now an operator). This is because in update.formula the
call to terms.formula uses simplify = TRUE. I'm working with data that

Help with hclust() and plot()
Hi
When I use plot(hclust(dist..)...)...) etc to create a dendrogram of a
hierarchial cluster analysis, I end up with a vertical tree. What do I
need to do to get a horizontal tree?
Also, my users are used to seeing trees who's leaves all "end" at the
same place (eg. Like in minitab). Is this possible in R?
Thanks

scatter plot with axes drawn on the same scale
Dear useRs,
I'd like to produce some scatter plots where N units on the X axis are
equal to N units on the Y axis (as measured with a ruler, on screen or
paper). This approach
x <- sample(10:200,40) ; y <- sample(20:100,40)
windows(width=max(x),height=max(y))
plot(x,y)
is better than plot(x,y) but doesn't solve the problem because of the
other parameters (margins etc). Is

r-2.13 fails make check
I am only reporting this because it is the current release branch and
not devel.
R-2.13 from svn revision 55957 builds fine, but fails make check.
This happened with a fresh svn checkout 12 hours ago and it still
happens as of now. Two days ago I could build R-2.13 and it passed
make check on the same system, so I doubt it is a system problem. But

changes to terms.formula in 2.3.x
Hi, all,
I just recently noticed a change in terms.formula from 2.2.1 to 2.3.1
(possibly 2.3.0, but I didn't check). Here's the problem:
## 2.2.1
> update(~ x | y, z ~ .)
z ~ x | y
## 2.3.1
> update(~ x | y, z ~ .)
z ~ (x | y)
and in the NEWS for 2.3.1

terms containing '|'. (PR#8462)

convert large integers to hex
Hi,
I'm wondering if someone has solved the problem of converting very
large integers to hex. I know about format.hexmode and as.hexmode, but
these rely on integers. The numbers I'm working with are overflowing
and losing precision. Here's an example:
x <- "6595137340052185552" # stored as character

Anyone can tell me how to generate "A01", "A02", ..., "A99"?

Revision: post on Intro to R lecture
Hi All:
This follows my earlier post on webized slides on lecture presentation on introducing R. I learned that in Mozilla (Firefox) browsers, the slides did not show up. Sorry for the no show. As a reluctant windows user, I kind of carelessly clicked through Powerpoint to convert the presentation file to its html form, unwittingly leading to the mess.
See if it got corrected now (I do not have
