"break" breaks _outer_ loop -- ugh!
It appears that "break" will break from the outermost enclosing loop not
the innermost loop. Is it a bug or language feature?

postgresql package for R
A preliminary release of my postgres package for R is at
http://www.nceas.ucsb.edu/~keitt/R/postgres.tgz
It allows one to read and write data frames to and from a postgres
database, execute queries and has an experimental "proxy" interface that
allows you to access postgres tables using the standard, local data
frame model. All accesses to the data frame generate the appropriate

save/load hooks
I'd like to suggest a small feature be added to R. It would be nice if
"load" and "save" had function hooks for object initialization and
finalization, e.g.,
load.hook <- function(x) UseMethod("load.hook")
save.hook <- function(x) UseMethod("save.hook")
These would then be called on each object saved or loaded. The default
method would do

0.99
Congrats on the new release. The new package management tools are
great!
A couple of quick comments:
1) it might be nice to add an optional "Autoloads:" field to the
description (the package does not depend on these other packages, but
will autoload them if certain functions are called).
2) on page 3 of the R-exts document, it says to set PKG_* flags in
'Makeconf'; I think

lapack routine dgesdd, error code 1
Hello R-users,
during one of my analyses that involve a SVD, I get the following error
message:
Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine

With a search on the R web site, I only found references to error codes
17 and 3 for this particular routine. I also found the Lapack web site,
but could not find a list of the possible error messages. If somebody

Superimposing vector polygons over raster grid in a plot
Hello:
I would like to superimpose vector polygons (state outlines) from a
Shape file on top of a satellite image,
imported into a SpatialGridDataFrame from GEOTIFF via gdal_translate and
readGDAL.
When I plot polygon and point shape files in R, into
SpatialPointDataFrame and SpatialPolygonDataFrame,
the two feature sets line up geographically, so it seems logical that a

More plotting comments
None of this is greatly important but might be a bit useful to someone.
BTW, I have 0.99a installed, it compiled without a problem.
I've discovered most of the plotting facilities including the legend()
function and the various text annotations, this is nice an convenient
and flexible enough to do most things. One thing that I must say is that

comparing execition time: R vs matlab linear algebra...
Greetings:
We are evaluating the performance of R matrix algebra es as we port a
MATLAB R14 script into R.
The MATLAB code basically evaluates the AX=B system on sparse matrices
that result in output matrices of 100 to 1,000,000 rows/columns.
Our R prototype script uses spase base matrices and the methods qr() and
qr.coeff().
The following statements are called inside a doubly-nested loop:

Anything for fractals ?
Hallo,
I am a newbie to R and desperatley seeking some material about fractal
geometry. I found the great library on wavelet analysis of images and
I'm now also keen on finding a similar package for calculating fractal
parameters for given images.
Does anybody know something about such a package? Every hint is greatly
appreciated!! I searched already the database, but did not find anything

Pros and Cons of R :GUI
R has very good GUI packages that I have used -
R Commander RCmdr and Rattle rattle . Since I work on multiple packages with
constraints of time, I almost always use the GUI rather go through the
intricacies of command line .
The log of these GUIs shows the relevant R command that was used, so you can
actually learn the language also.
I have written about the ease of learning R , if you begin

Object finalization
I see some code in R to attach finalizers to external pointer references
(Register[C]Finalizer). Anyone have an example of how to code the
finalizer? R_RegisterCFinalizer accepts a C function, but I can't see
how to get it to operate on the pointer, since the pointer is not passed
to the function when its called. RegisterFinalizer takes an R closure,
but how is it called from R (tried

again on ubuntu 7.10 and amd64
Hi there,
this is my first post to the list.
I'm a newcomer to the linux world.
I started using it on a regular basis on May and I must say I'm quite
comfortable with it, even if I have to re-learn a lot of things.
But this is not a problem, I will improve my knowledge with time.
My main problem now is that I bought myself a new computer (described at
the end of this e-mail) and I was

mulitmodal distributions
Hello,
I see that "mclust" is a pacakge that handles fitting mixtures of normals.
Are there any other packages out that that can handle mixtures of gammas or
other exponentials?
Additionally, are there any packages out there that can fit bimodal
distributions without mixtures? i.e., Cobb et al. 1983 using moment
recursion relations?
Thank you!

try FlexMix RE: mulitmodal distributions
Hi, Marion,
I believe the package FlexMix provides a more generalized version of
finite mixture modeling than is found in mclust/mclust02.

Matrix subscripting to wrap around from end to start of row
Perhaps it is just that I don't even know the correct term to search for,
but I can find nothing that explains how to wrap around from the end to a
start of a row in a matrix.
For example, you have a matrix of 2 years of data, where rows are years, and
columns are months.
month.data = matrix(c(3,4,6,8,12,90,5,14,22, 8), nrow = 2, ncol=5)
I would like to take the average of months 5:1 for
