limits on liniar model
Can I put limits on the lm() command? I only know that you can choose a
liniar model with or without an intercept, but can I put other limits on
the coefficients (for example- the intercept must be bigger than 1) ?

Regrouping data
Dear R forum
I have just started my venture with R. While I am trying to learn R through the tutorials, I think the current problem I need to address to is beyond my knowledge about R.
I have a dataframe as defined below -

[LLVMdev] llvm-gcc-4.2 vs gcc 4.4
In order to see how llvm-gcc-4.2 svn performs in code generation
compared to the upcoming gcc 4.4, I ran the Polyhedron 2005
benchmarks on a MacPro with the -ffast-math -funroll-loops -msse3 -O3
optimization flags for both compilers. The results are summarized
below.

[LLVMdev] gfortran benchmarks
Since the fact that gfortran performance has improved

are...

Trouble about the interpretation of intercept in lm models
Hallo,
yesterday I was puzzled when I discovered that I
probabliy miss something in the interepretation of intercept
in two-way lm models.
I thought that the intercept, using the default contr.treatment
contrasts, represents the mean of the group of observations
having zero in all column of the model.matrix.
It turns out not to be case
To be more more clear I am attaching a short example:

performance of apply
I noticed that apply is VERY SLOW when applied to a "large"
dimension as for example when computing the row sums of a matrix with
thousands of rows.
To demonstrate it, I did some benchmarking for different methods of
computing the row sums of an nx10 matrix with n =3D 2000, ..., 10000.
The first method (M1) I used is the normal apply command:
y <- apply(x,1,sum)

Forward Selection with regsubsets

I would like to perform a forward selection procedure on a data set

regsubsets (I set nvmax=number of observations) but I keep getting

save() object w/o all of the loaded environment
I have two packages, one that does the actual work (SC) and the other
a Tcl/Tk UI (SCUI) that invokes methods within the former. Within the
SCUI's invocation method, I save an object returned from SC, the
results of a long-running method.
Now the object is completely described by the SC package. Unfortunately,
any attempt to load the object (in a fresh R session) fails as below.

Can we do GLM on 2GB data set with R?
We are wanting to use R instead of/in addition to our existing stats
package because of it's huge assortment of stat functions. But, we
routinely need to fit GLM models to files that are approximately 2-4GB
(as SQL tables, un-indexed, w/tinyint-sized fields except for the
response & weight variables). Is this feasible, does anybody know,
given sufficient hardware, using R? It appears to

how to store package options over sessions?
Hi,
I posted this a week ago on r-help but did not get an answer. So I hope that someone here can help me:
I want to define some options for my package the user may change.
It would be convenient if the changes could be saved when terminating
an R session and recovered automatically on the next package load.
Is that possible and if yes, is the standard way to implement this?
Thanks,

patche for samba-2.0.7/source/smbd/conn.c
Dear all,
I have made patch for samba-2.0.7/source/smbd/conn.c
This will, instead of using by-directional link, use
array for managing connections.
# The patch does seems to work on my RHL6.1Ja(fixed) version of
# Linux machine. I don't know about other OS/Architecture.
This should work better then original because:
