I just downloaded R-1.1.0.tgz and attempted installation as usual with

Dumping functions to RCS
To keep track of an ongoing programming project, I would like to dump
all my functions to individual ASCII files named xxx.R, yyy.R, etc.
Presently I do so manually in order to use RCS (on a Linux machine),
so I can keep track of all versions, differences, snapshots, etc.
Is there any easy way to dump all functions in the workspace to
individually named files? Thank you very much for

Compiling R on an Alpha
Sorry to be such a nuisance but after asking for help with compiling
R-1.1.0 on an Intel-based machine I now have another problem on the
Alpha DS-10 server which my students use.
Compilation and instalation proceed perfectly, but when I invoke R I
get:
[etdx01:bin]$ ./R
Fatal error: The X11 shared library could not be loaded.
The error was /home/etptupaf/R/lib/R/bin/R_X11.so: undefined

Sampling from a database
I use RODBC and RpgSQL quite a lot to access files stored in another
machine under PostgreSQL. Since I am now using files which do not fit
into R's memory, I would like to take random samples. What I would
like is to issue a query such as
SELECT * FROM file WHERE runif > 0.9
with "runif" being a uniformly distributed random number, generated on
the fly; but I cannot

Multivariate response trees
I would like to know if someone has done work on trees with
multivariate response. I need something like rpart but for vector
responses. If someone has code that he/she is willing to share, I
would be grateful. If not, even guidelines for writing my own starting
from rpart would be welcomed.

Ordered factors and DBMS
Is there any way of preserving order of ordered factors when storing a
table in PostgreSQL?
I have been using PostgreSQL and the RPgSQL package to store a large
table with answers such as "Strong disagreement", "Strong agreement",
"Mild disagreement". "Mild agreement". When reading the table, such
answers are turned into factors, apparently in

"Attach" for S4 objects?
When passing a list as an argument to a function, I find it convenient
to attach it in the first line of th function code, then refer to the
components as A, B, etc. rather than as list$A, list$B, etc.
If I pass a S4 class object, is there a way to "attach" it, or do I have
to refer to the slots as object at A, objetc at B, etc.?
I could always make copies,
A <- object at A

Princomp(), prcomp() and loadings()
In comparing the results of princomp and prcomp I find:
1. The reported standard deviations are similar but about 1% from
each other, which seems well above round-off error.
2. princomp returns what I understand are variances and cumulative
variances accounted for by each principal component which are
all equal. "SS loadings" is always 1.
3. Same happens

Aligning aerial photographs and maps
I have read in Paul Murrell's book R Graphics about how to use a bitmap
as background for a plot (page 107). Also, I routinely use function
read.shape() in package maptools to read maps in shapefile format. Now,
I would like to overlay an aerial photograph in .jpg format and a map. I
think I could do the alignment manually for each case, but wonder if
there is a better, automated way. I notice

Cannot read .rda data
Below the line is (slightly edited, to remove irrelevant stuff) the
transcript of a session in R. Seems that data is read in, but I cannot
print or use it.
I have looked inside the data directory of MASS, and see that the
format of the data is different than the one from other libraries I
have. It may be that this particular format is not read correctly, or
my setup may be faulty. I

Hi
I would like to start by thanking everyone that replied. Thank you for the
information, and for the comments about how or why you use it and thankx for
the encouragement re my talk....
Please note that I do not claim to have ellicited a reply from all users of

R-1.1.0 on Alpha?
Has anyone succeeded in compiling R-1.1.0 on a Digital (Compaq) Alpha

scent for a while!), but then at run time I get:

"Glueing" factors together
Hi folks,
Suppose I have a series of cases each with categorical
factors A, B.
What is the best way to "glue" A and B together into a single
factor? For example, given
A0 B1 ...
A1 B1 ...
A0 B2 ...
A1 B0 ...
A0 B0 ...
A1 B2 ...
then I'd like to end up with a single factor with levels
A0B0, A0B1, A0B2, A1B0, A1B1, A1B2
according to all the combinations which actually occur in

recursive penalized regression
Hi,
Few days ago I posted a question to r-sig-finance, which I thought would
be an easy one. To my surprise I have received no replies, which makes
me think that it is either harder than I thought, or that it makes no
sense. I am reposting the message (with some modifications) on the
R-help in a hope to get some leads, suggestions for alternatives, etc.
My apologies to those who had seen this on
