Is anyone using these softwares in Wine ? Does it work ? Pasquale

Hello fellow R users, I have an issue that has me a little confused - sorry if the subject makes little sense, I wasn't sure how to refer to this problem. I have a data set I've extracted from ArcInfo (a section is shown below). It is spatial data, showing the distance from one ID to another. I want to get the actual 'TO' ID from the data set (there is no easy way to do this in Arc so I thought I would try in R). The way to do this is to find the dist = 0 row for an ID then that is that...

I don't think so. The library is just a heap of function to access to the data in the binary coverages. I know plotpoly is REALLY slow. For example, plotting the map of Austria takes about 5-10 minutes in my computer (an Athlon 1.4 MHZ,...

...nt and spatial packages become more and more powerful. Look here for most recent development: http://www.r-project.org/Rgeo R can currently read (relevant R package name in brackets: ASCII grid (with custom function or Adehabitat), shape files (maptools and shapefiles), GRASS files (grass) and ArcInfo files (RArcInfo), many others via external gdal (rgdal). I would say plenty of opportunities! Hope this gets you under way! Cheers, Sander.

What tools and documentation exist for producing maps and working with polygon and polylist objects in R beyond the following: * Packages maps, mapproj, maptools, and mapdata. * Becker and Wilks (1993, 1995), listed as references in the documentation on the "map" function. Thanks, Spencer Graves

Dear Sirs: I am not yet a user of R. My background includes the use of (Turbo) Pascal for scientific analysis of underwater acoustics problems (e.g. sound ray tracing and array gain in directional noise fields.) I have become interested in the following type of problem: (1) select , say, 1000 random locations within the continental United States; (2) characterize (statistically) the

Dear all, I am interested in plotting maps visualizing spatial statistics in an aggregated fashion, according to administrative boundaries. Partially, I want to visualize some spatial data for administrative units (autonomous republics, oblasts, krays) of the Russian Federation on a geographical map. I have found the maps package (and related) and would like to use this package e.g. in a kind

If _you_ were asked to give a 40 minute dog and pony show about R for a group of scientists ranging from physicists to geographers what would you put in? These people want to know what R can do. I'm thinking about something like: A. Overview B. data structures C. arithmetic and manipulation D. reading data E. linear models using glm F. graphics G. programming H. other tricks like rpart or

...can compiled using the MINGW C compiler, that is recomended by B. Ripley to compile R under Windows. The other questions are: - How can I open/close connections directly from C/C++? - Do you know about a free Visual Basic compiler? The final purpose of using R-(D)COM is to create a link between ArcInfo and R, in the same way 'S-Plus for ArcView' does. Thank you in advice.

The main limitation of the shapefiles package that I put together is that it does not create shapefiles from R objects - rather it only writes shapefiles that have been read into R and manipulated within the constraints of the existing file structure. By this I mean that for example you can change the coordinates of points and write them back out. Or you can add a bunch of blank columns in the

Salutations: I have been trying to translate a S-PLUS/ArcInfo (GIS software) application that I wrote on a SGI (IRIX) platform to public domain R and GrassGIS on a Linux platform. I am almost on the verge of abandoning it as I find R to be rather unstable, slow and frustrating. I enclose a section of my code for R experts to examine hoping that they'll p...

Dear listers, I was used to package pgirmess under Windows with everything OK, but, for the first time, I had a trial this afternoon on Ubuntu 7.10 gutsy (I have a double boot computer and work more and more under unix) and R 2.7.0. Everything went OK except this: sudo R CMD check pgirmess ..... * checking examples ... ERROR Running examples in 'pgirmess-Ex.R' failed. The error most
