Newbie seeking directions
Hello everybody,
I'm developing the www.polyxmass.org (GNU polyxmass) program that is a
polymer sequence editor (a polymer is a thread made of concatenated
monomers).
I would like to code a "self-speak-out" feature for that sequence
editor: the user would select a sequence region and ask that the
program would "dictate" the sequence.
For example, the following could be

Failing on reading a "slightly big" dataset

Max. :9.558e+06 Max. : 2.004e+08

Sniffing, I find that the last observation in the data frame `firms'
is wonky:

where we see that YOUNG POLYMERS was observation 88,904 in the
file. How did it become #38249 to R?

Approximate taylor series
Hi All,
Say I have the values of function f(x1,x2,x3,x4) for each values of
x1,x2,x3,x4 but not complete. But the functional form is not known.
Techniques like regression, etc. are not able to give me satisfactory
results and msy be more complex than we thought.
I wanted to use Taylor's approximation to continuous function, to
approximate a functional form using the given data. But failed

Quadratic function with interaction terms for the PLS fitting model?
Hi Bert,
Ok, to your initial point, the key nuance is that if 'x' is a vector, you can leave the 'degree' argument unnamed, however, if 'x' is a matrix, you cannot. That aspect of the behavior does not seem to change if poly() is called stand alone or, as suggested in ?poly, within a formula to be parsed.
Working on tracing through the code using debug(), the error is

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.

Quadratic function with interaction terms for the PLS fitting model?
Marc:
1. I am aware of the need to explicitly name arguments after ... --
see the R Language definition where this can be inferred from the
argument matching rules.
2. I am aware of the stated exception for poly(). However:

> x2 <- runif(20)
> mx <- cbind(x1,x2)

polynomial expansion in R
Hi:
I have two vectors of data, x and y and I want to get the "polynomial" expansion of (x+y)^p with any integer power p in R. Suppose p=2, then I want a matrix of five vectors, namely, x y x^2 y^2 x*y. The coefficient of the polynomial is not needed. I can write it manully if p is small. But I want it in the case of p=10 or even bigger, is there any function in R can do that

problem with rJava : same as message from wwreith on Mon, 27 Jun 2011
Hi R-listers,
I run R version 2.13.0, on a i386-pc-mingw32/i386 platform under Windows XP.
I perform daily update of my installed packages.
I've got the most recent Java for this platform installed, as I am told
by the JavaUpdater when checking.
(and I've read the posting guide, so that I'm not going to get fired by
Uwe as poor wwreith [joke])...

Solve an ordinary or generalized eigenvalue problem in R
...ickly and it could be a nice summer or term
project for a student (Google Summer of Code 2013?). I'll be happy to kibbitz and mentor,
but I'd rather stay on the sidelines of actual package building, as I no longer have a
direct need. My application was the quantum electronic structure of polymers in 1972/3.
However, I think the code is still reasonable.
Best, JN

plot method for rasters and layout
Hi list,
I thought I was used to layouts, but today I am facing a problem I cannot
overcome :
On my R installation (Windows 7 Pro, SP1, R version 2.13.0, daily update of
packages), I am not able to put raster plots in user defined layouts :
> layout.matrix<-matrix(c(1,2,3,4,5,5),2,3)
> layout(mat=layout.matrix)
> layout.show(5)
works fine, I get the correct frames in
