Re: [R] Running an R script without running R
Alberto, Below I have two scripts: (1) cpc2fgroup (2) R.cpc.6_10day.outlook.batch Bash shell script (1) calls the R script (2). (1) also sets some environment variables for (2). I make no claims that this is good coding and I might write things a little differently now (rather than a few years ago), but it works… Also, there are some things going on with GRASS GIS that probably has no relevance to your needs, but I also read data from GRASS GIS and have to set some environment variables for it too, I hope this helps and is not confusing.

Interactively, within a R session, I can simply re-size the graphics window and all the labels appear. But, what can I do non-interactively to have all the labels displayed when using Sweave?

[R] Normal score transform of spatial data
List: I have 2 related questions: (1) first I have x-y-z data, where x & y are the geographic locations of point values, z. I need to perform a normal score transform on the z-values and maintain their geographic location. So, how do I go from columns x-y-z to x-y-z-t (or x-y-t), where the t-values are the normal score transforms of the z-values? Can I use qnorm(ppoints(data)) to do this; how? (2) I also need to do a reverse transform of a matrix of normal score values (v) to my original data value units; I have seen that I can use something like approx(t, x, v)$y. Again, the matrix represents a spatial grid. So, how do I maintain the same spatial ordering resulting from the reverse transform? Thank you for your help.

Re: [R] use of R in big companies (references) & R-support esp in Germany
Spencer, I agree that there exist biases within large organizations toward commercial software packages, but I humbly disagree that this can be reduced to geopolitical differences. I work for a US Government Agency and while there is some truth to the feeling "[they] refuse to believe that anything free can be any good", it has little-to-nothing to do with Capitalism vs whatever… I think the feeling has to do more with the *perceived* issues related to support and what is "tried & true" — it's a very conservative approach, one that I face on nearly a daily basis. Apart from my use of R, I am also a heavy user of the open source Geographic Information System (GIS) called GRASS, in which the *dominant* GIS company internationally is ESRI and their very expensive software called ArcGIS. There is very little that ArcGIS can do that GRASS can not do. What is especially troublesome is that ArcGIS is restricted to the MS-Windows platform, whereas GRASS runs on Linux, MacOS X, UNIX, and MS-Windows with Cygwin. Thank you for your references as I hope to use them.

Re: [R] multiple comparisons of time series data
Kyle, You might try the Wilcoxon Rank Sum test (and there is also the paired rank sum test) that may be useful. Both are found in R. There is an application of the test in the textbook by Loucks, D.P., Stedinger J.R., and Haith, D., 1981. "Water Resources Systems Planning and Analysis", Prentice-Hall, Eaglewood Cliffs, New Jersey. I hope this helps… Go HOKIES!

[R] Problem installing rgdal from source -- Makevars issue
List: I have installed R, contributed packages, and supporting libraries in a non-standard location (but under the same sub-directory tree). This was necessary for systems reasons beyond my control. When I attempt to use Makevars (as shown below) to install rgdal from source, I get the following error: R CMD INSTALL rgdal_0.4-3.tar.gz . . . checking proj_api.h usability... no checking proj_api.h presence... no checking for proj_api.h... no libproj.a and proj_api.h not found in standard search locations, edit src/Makevars manually, adding -I to PKG_CPPFLAGS = , and -L to PKG_LIBS = ERROR: configuration failed for package 'rgdal' ** Removing '/awips/rep/lx/local_apps/R/lib/R/library/rgdal' ** Restoring previous '/awips/rep/lx/local_apps/R/lib/R/library/rgdal' I get this error regardless of where I put the Makevars file: $HOME/.R/Makevars, in the local build directory, or in the rgdal source directory src/Makevars runing ./configure My Makevars contains this: PKG_CPPFLAGS = -I/awips/rep/lx/local_apps/proj4/include PKG_LIBS = -L/awips/rep/lx/local_apps/proj4/lib I have also tried using the file name: Makevars and Makevars-i686-pc-linux-gnu I'm sure I am doing *something* wrong; any suggestions?
