DGESDD from Lapack for R-1.4.0?
...'t
want all the singular vectors; and add ZGESDD also).
Though what I've done so far would probably be trivial for
someone who knew what they were doing...
Mac G4, 450 MHz, LinuxPPC, pre-compiled ATLAS-3.2.1
libraries for G4 from www.netlib.org, R-1.3.1:
> m <- matrix(rnorm(25e4), 5e2, 5e2)
> system.time(svd(m))
[1] 22.31 0.10 23.01 0.00 0.00
> system.time(La.svd(m))
[1] 29.60 0.10 29.78 0.00 0.00
> system.time(La.sdd(m))
[1] 7.28 0.12 8.00 0.00 0.00
Thanks, Keith Richards-Dinger
P.S. I would have checked if DGESDD is in r-devel but I
could not figure out how...

model R^2 and partial R^2 values
Dear R-list members,
I am doing a CART analysis in R using the rpart function in the rpart package:
Phrag.rpart=rpart(PhragDiff~., data = Phrag, method="anova", xval=10).
I used the xerror values in the CP table to prune the tree to 4 nsplits:
CP nsplit rel error xerror xstd
1 0.098172 0 1.00000 1.02867 0.12768
2 0.055991 3 0.70548 1.00823 0.12911

ordering dataframe for strata() (PR#13830)
...epeated measures that are not sorted in
order the run will fail on a given stratum. Ordering the dataframe
prior to using strata() eliminates this problem.

but still get the same thing.
Also, as R starts, I get a bunch of dialog boxes that complained about DLL
relocated. Is this normal?
If I just type "c" and run Rgui, and issue the command
"La.svd(matrix(runif(5e4), 5e2, 1e2))", I get a few more dialog boxes, one
saying "Invalid address specified to RtlFreeHeap(9f0000, 1efde80)", another
saying "HEAP(Rgui.exe)", and a SIGTRAP is generated.
I did one more (crazy? stupid?) thing: I replaced the lapack.c in R-devel

Hello All,
I'm trying to set up linux ssh/shell authentication on a CentOS_6.2 server

Uwe, thanks for helping! After some poking around, I realized that the
problem was that I had installed OpenBUGS instead of WinBUGS. I did an
