A preliminary release of my postgres package for R is at http://www.nceas.ucsb.edu/~keitt/R/postgres.tgz It allows one to read and write data frames to and from a postgres database, execute queries and has an experimental "proxy" interface that allows you to access postgres tables using the standard, local data frame model. All accesses to the data frame generate the appropriate

The current INSTALL script calls ./configure if it exists when installing packages, but does not check the return value from configure. I have my configure script abort under certain conditions and it would be nice if the INSTALL script would stop at that point. Also, is there an autoconf macro for testing for gnu make?

I'd like to suggest a small feature be added to R. It would be nice if "load" and "save" had function hooks for object initialization and finalization, e.g., load.hook <- function(x) UseMethod("load.hook") save.hook <- function(x) UseMethod("save.hook") These would then be called on each object saved or loaded. The default method would do

Congrats on the new release. The new package management tools are great! A couple of quick comments: 1) it might be nice to add an optional "Autoloads:" field to the description (the package does not depend on these other packages, but will autoload them if certain functions are called). 2) on page 3 of the R-exts document, it says to set PKG_* flags in 'Makeconf'; I think

Hello: I would like to superimpose vector polygons (state outlines) from a Shape file on top of a satellite image, imported into a SpatialGridDataFrame from GEOTIFF via gdal_translate and readGDAL. When I plot polygon and point shape files in R, into SpatialPointDataFrame and SpatialPolygonDataFrame, the two feature sets line up geographically, so it seems logical that a SpatialGridDataFrame

Hello R-users, during one of my analyses that involve a SVD, I get the following error message: Error in La.svd(x, nu, nv, method) : error code 1 from Lapack routine dgesdd With a search on the R web site, I only found references to error codes 17 and 3 for this particular routine. I also found the Lapack web site, but could not find a list of the possible error messages. If somebody knows what

Hallo, I am a newbie to R and desperatley seeking some material about fractal geometry. I found the great library on wavelet analysis of images and I'm now also keen on finding a similar package for calculating fractal parameters for given images. Does anybody know something about such a package? Every hint is greatly appreciated!! I searched already the database, but did not find anything

None of this is greatly important but might be a bit useful to someone. BTW, I have 0.99a installed, it compiled without a problem. I've discovered most of the plotting facilities including the legend() function and the various text annotations, this is nice an convenient and flexible enough to do most things. One thing that I must say is that the help pages on plot() and plot.default()

Hi, I am doing a very informal presentation for my office about R capabilities to deal with and analyze spatial data, display data and maps, and connections with GIS. I've used in my presentation info from the CRAN, the spatial Task view, and the more striking graphics examples from http://addictedtor.free.fr/graphiques/thumbs.php and NCEAS

Greetings: When using R within GRASS6, and loading the rgdal library, I encounter an error loading a specific version of the HDF5 library that does not occur when I perform the same operation in R 'outside' of GRASS6: Here is a record of the error on my ubuntu system: ---------- Start --------- reeves at wallace:~$ grass2 Cleaning up temporary files.....

Perhaps it is just that I don't even know the correct term to search for, but I can find nothing that explains how to wrap around from the end to a start of a row in a matrix. For example, you have a matrix of 2 years of data, where rows are years, and columns are months. month.data = matrix(c(3,4,6,8,12,90,5,14,22, 8), nrow = 2, ncol=5) I would like to take the average of months 5:1 for

Hi there, this is my first post to the list. I'm a newcomer to the linux world. I started using it on a regular basis on May and I must say I'm quite comfortable with it, even if I have to re-learn a lot of things. But this is not a problem, I will improve my knowledge with time. My main problem now is that I bought myself a new computer (described at the end of this e-mail) and I was

Greetings: We are evaluating the performance of R matrix algebra es as we port a MATLAB R14 script into R. The MATLAB code basically evaluates the AX=B system on sparse matrices that result in output matrices of 100 to 1,000,000 rows/columns. Our R prototype script uses spase base matrices and the methods qr() and qr.coeff(). The following statements are called inside a doubly-nested loop: G

I see some code in R to attach finalizers to external pointer references (Register[C]Finalizer). Anyone have an example of how to code the finalizer? R_RegisterCFinalizer accepts a C function, but I can't see how to get it to operate on the pointer, since the pointer is not passed to the function when its called. RegisterFinalizer takes an R closure, but how is it called from R (tried

R has very good GUI packages that I have used - R Commander RCmdr and Rattle rattle . Since I work on multiple packages with constraints of time, I almost always use the GUI rather go through the intricacies of command line . The log of these GUIs shows the relevant R command that was used, so you can actually learn the language also. I have written about the ease of learning R , if you begin
