Converting expression to a function
Previously, I've posted queries about this, and thanks to postings and messages in
response have recently had some success, to the extent that there is now a package called
nlmrt on the R-forge project https://r-forge.r-project.org/R/?group_id=395 for solving
nonlinear least squares problems that include small or zero residual problems via a
Marquardt method using a call that mirrors the nls()

Executing R scripts from another R script
Hello, everyone
I run Eclipse Ganymede and R 2.7.2 at work.
I have one R script file where I open in memory a new xls file (using
xlsReadWritePro), call other R scripts, which are in the same folder
as the main R script,
which get data from an existing xls file, process data, and output
results in the xls file which is in memory.
That is the idea. But I cannot make it work.

how can I read a non-standard XLS file
I have attached a file downloaded from database mirWalk.
Apparently it is in XLS format (this is the extension of the downloaded file).
However, I cannot open it with OpenOffife spreadsheet program and Excel itself
cannot separate the columns as it does when a true XLS file is loaded.
I tried to read the attached downloaded file through R function "read.xls"
and got the following

Implementation of the PL2 weighting scheme of the DFR Framework
Hello guys.I am working on implementing the PL2 weighting scheme of the DFR
framework by Gianni Amati.
It uses the Poisson approximation of the Binomial as the probabilistic
model (P), the Laplace law of succession to calculate the after effect of
sampling or the risk gain (L) and within document frequency normalization
H2(2) (as proposed by Amati in his PHD thesis).

Ouput several lines of cat
Hello,
I am brand new to R. I need to know how to output the contents of cat
function into a text file. The cat is used to output several lines of string
in the following format:
X XXX
X XX.XX
XXXX-XXXX ( XX.XX XXX )
I need to get the output of all these lines into a text file.
I tried to put a file name in the cat function. However the output file only
displays single line output.
Thanks

Help on simple problem with optim
Dear all,
I ran into problems with the function "optim" when I tried to do an mle estimation of a simple lognormal regression. Some warning message poped up saying NANs have been produced in the optimization process. But I could not figure out which part of my code has caused this. I wonder if anybody would help. The code is in the following and the data is in the attachment.

newton.method
Hi,
Is this method broken in R? I am using it to find roots of the following
function:
f(x) = 2.5*exp(-0.5*(2*0.045 - x)) + 2.5*exp(-0.045) + 2.5*exp(-1.5*x) - 100
It is giving an answer of -38.4762403 which is not even close (f(x) =
2.903809e+25 for x=-38.4762403). The answer should be around 0.01-0.1. This
function should converge..
Even for a simple function like f(x) = exp(-x) * x, it gives

behaviour of xls2sep when running read.xls (package gdata) sinceupgrade of R
Hello eveRybody (and probably special regards to Gabor G....),
I recently upgraded from R-2.9.2-win32 to R-10.1.0-win32, and I'm using
Windows XP Professional 2002 with service pack 3 on a PC with IntelCore
Duo CPU@ 3.00 GHz.
