alternatives to traditional least squares method in linear regression ?
...I'd like to stay with something linear.
Has anybody already implemented a function or package in R allowing to
modify the exponent (of the least squares method) or more general
allowing to define the model to be used for estimating/optimizing the
residues ?
Thank's in advance

optimizing speed of calculation (recursive product)
...processes, but in this case I don't see how I could do so.
a <- runif(10000000,0.5,1.6)
C <- 2
M <- 10000000
system.time( for (i in 1:(M-1)) {C <- C* c(a[i],a[i+1])} )
By the way, I'm using R-2.7.2 on Win XP and/or Fedora Linux.
Thank's in advance for any hints,

Problem with .libPaths & Rterm.exe (under Vista)
...ngle path is found, which is the default
collection of libraries in the path of the R installation itself.
Does anyone have an idea how I could identify the libPath for a given
user and by which argument added to R.exe I could allow accessing these
libraries, too ?
Thanks? in advance,
Wolfgang Raffelsberger

Package RODBC
I have some questions about the RODBC package.
library(RODBC) # required for those who want to repeat these lines
1st, I noticed that the following sequence does not work:
channel <- odbcConnextExcel("test.xls")
tables <- sqlTables(channel)
name1 <- tables[1, "TABLE_NAME"] # this should be the name
plan1 <- sqlFetch(channel, name1) # bang!

using Sweave, how to save a plot in a given size
Hi,
I'm trying to realise a repport with R and Latex (TeXnicCenter and Miktex for Windows) using Sweave().
I'd like to save my plots in a given size. How can I do that ? The code is :

<<partI, echo=FALSE ,fig=TRUE, include=FALSE>>=

replace values of a table !!!
Dear all,
Dear all,
I am a relatively new user.
I have an ascii file with 550 rows and 400 columns. The file contain values ranging from 1 to 2000 and some values with -9999.
I want to generate a new file where the -9999 values are replaced with 0 values, the other values with the 1.0 value.
What should I do,
Thanks

path for source()
hello,
i have a couple of .R files distributed about my file system. i commonly source() these from other files, but i have to include the full file path. this is not always convenient if you move files around. is there a way of setting the search path for source()?
thanks a lot!
cheers,

Sweave: Conditional code chunks?
I have a code junk that produces a figure. In my special case,
however, data does not always exist. In cases where data exists, the
code chunk is of course trival (case #1), however, what do I do for
case # 2 where the data does not exist?
I can obviously prevent the code from being executed by checking the
existence of the object x, but on the Sweave level I have a static
figure chunk. Here an
