Hi everyone, I have written a class with methods that extend generic functions such as as.data.frame or show. When I load this package, I want to ensure that these methods - along with the other functions in the file - are added to R's search path or updated, if necessary. I have made a package using check/build/INSTALL. Will a simple library() call on the package accomplish this? I

Maintainer: Doug Nychka <nychka at ucar.edu> I have an IOAPI (netCDF classic plus spatial metadata) dataset with structure {cols, rows, layers, timestep=1}, where {cols,rows} represent a land-cover grid.

Does anyone know of contributions to R for solving sparse linear systems? In particular for spatial stats I am interested in solving large positive definite symmetric systems.

Hi, is there anybody knowing a possibility to produce a legend (describing the color scheme) in an image plot in R. In S-Plus this works using image.legend. Thank's in advance.

summary: how to make image.plot print a subtitle between the title and the image, rather than under the image? details: I've got a project https://github.com/TomRoche/ioapi-hack-R that illustrates the use of (et al) the R packages {ncdf4, fields, M3} for processing and visualizing IOAPI data. The data being visualized consists of a series of layers (mostly representing emissions from a

Hi, I have a 4 column file (long/lat/elev/variable) and I tried to fit the values of my variable to the XYZ space using Tps and I keep getting the following message: Warning messages: 1: GCV search gives a minumum at the endpoints of the grid search in: Krig.find.gcvmin(info, lambda.grid, gcv.grid$GCV, Krig.fgcv, 2: GCV search gives a minumum at the endpoints of the grid search in:

Hi, I spotted an inconsistency between the output of funfits under R, more specifically "nnreg", and the one obtained under S-plus. Notice the difference in the "Root MSE", "GVC" and "GVC cost=2". As a check mark, I am also including the data summaries, confirming that I was in fact using the same data set. Here's my output from both systems:

Dear all, Has anyone worked on coding for calculating Lyapunov Exponent for a time series data? or any package is available for computing Lyapunov? Please advice and many thanks in advance. Catherine X Wang

Dear useRs, I am using mgcv version 1.7-16. When I create a model with a few non-linear terms and a random intercept for (in my case) country using s(Country,bs="re"), the representative line in my model (i.e. approximate significance of smooth terms) for the random intercept reads: edf Ref.df F p-value s(Country) 36.127 58.551 0.644
