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 a...

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

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

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. Last time I used it (some weeks ago, before upgrading), one of my scripts (including the two lines cited below) used to run OK. When I ran it yesterday evening (after

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: > x1 <- runif(20) > x2 <- runif(20) > mx <- cbind(x1,x2) > poly(mx,2) Error in poly(dots[[i]], degree, raw = raw, simple = raw) : 'degree'

I'm running an analysis on Seedling survival (count data=Poisson distribution) on restoration sites, and my main interest is in determining whether the Nutrients (N) and water absorbing polymer Gel (G) additions to the soil substrate contribute positively to the survival of the seedlings, over a 3 year time period (for simplicity I'm just using 3 time periods, each in the same season for the 3 successive years). Fixed factors: Nutrients (0 and 1), Gel (0 and 1) Random factors: Site (4...

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

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])... But : since one of the last daily

Albricias. R 2.15.0 ha sido 'liberado'. La información de las novedades aquí: http://cran.r-project.org/src/base/NEWS.html Además, con esta versión empieza una nueva época, pues ya no habrá dos versiones por año, sino solo una con parches a lo largo del año. Que Vds. lo disfruten. -- :: Igor Sosa Mayor :: joseleopoldo1792 en gmail.com :: :: GnuPG: 0x1C1E2890 ::

...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.

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
