Hi all! Does anyone knows if it exists a "symbolic math" package in R, that allows to compute derivatives, integrals, etc.? Does exist a freeware version of Maple? Cheers, Marco [[alternative HTML version deleted]]

Hi, I have not been able to find answers to these questions in the FAQs, manuals, or R-help archives. If answers are available somewhere, please direct me to them. 1.) Is there a way to convert a table (e.g. represented as a data frame) to a function, specifying which columns are input and which column is output? It would seem that this would be useful for plotting experimental results,

Dear R users. I was wondering if you could help me with this error message I get when I try to install packages. I just installed R (the latest version, R 2.2.0) on my laptop (windows), and I was trying to install packages intwo ways: 1) Packages > Install Package(s)... 2) Packages > Install Package(s) from local zip files... , but in both ways I get the following error message:

#################################################################################### We have used maptools to construct state, county, township, census-tract, and zipcode level R maps with an Albers Conical Equal Area projection.

Dear R users, I am using spatstat to analyze point patterns (tree locations). I would like to import the shapefile with the study area polygons (six total) into R and use it to create the window for the spatstat analysis. I do not simply want to use a rectangle because the study areas spread out over 40000 ha. Any suggestions would be greatly appreciated. Thanks, Charlotte Reemts Charlotte

I'm just curious, but wondering if there has been any work in making these algorithms available in R. They are aimed at accelerating matrix-vector products using approximation ideas, and might be useful in applications such as kernel machines, Gaussian processes/kriging.

We're happy to announce the CRAN release of "sp", an R package which has new-style classes and methods for spatial data, version 0.7-9. Spatial data types that sp implements are: points, grids, lines, and polygons (i.e., rings) optionally with holes. Methods include + the usual print, summary, plot, [, [[, $, ... + coercion between types (e.g. points and grids, matrices,

I have distribution that are gaussian to a good approximation. I fit a gaussian to these distributons. Once in a while there is an outlier. Could someone suggest a robust method (R package already?) that removes those outliers and redoes the gaussian fit to get a better fit? Thanks. [[alternative HTML version deleted]]

I'll be even more tangent. Those interested in Ox, see http://www.de.ufpe.br/~cribari/ox.pdf Cheers, Francisco.

Hi, I am translating some Gauss code to R. Gauss has an interesting way of handling constraints. Observe the following code snipplet: e1 = x[.,23] .eq 0; @ remove obs with Regular Hours = 0 @ e2 = x[.,12] .gt 1; @ remove obs with non-regular work status @ e3 = x[.,4] .lt 15; @ remove obs with agricultural and mining industry code (< 15)@ esum = e1 + e2 + e3; e = esum .gt 0; @

The search at www.r-project.org mentioned a function "gauss.hermite{rmutil}". However, 'install.packages("rmutil")' produced, 'No package "rmutil" on CRAN.' How can I find the current status of "gauss.hermite" and "rmutil"? Thanks, Spencer Graves

Does R have something equivalent to the "goto" in Perl? If so, can you please tell me what it is? I cannot find it in the Ref Manual or the Language Manual. Thanks. - Warren Warren Lamboy USDA-ARS Plant Genetic Resources Unit Geneva, NY, USA 14456

Hi, I am trying to find a function that returns simply the weights and points of an n point gauss hermite integeration, so that I can use them to fit a non-standard likelihood. I have found some documentation for the function 'gauss.hermite' written by jim lindley, but can't find the actual binary on CRAN I'm aware there are lots of functions like glmm, glmmML etc to fit mixed
