Hello R-helpers, I'm trying to customize a graphic in lattice using the 'legend' argument to add labels on my plot but in the process I'm losing the legend drawn by 'auto.key', despite the fact that I'm actually not sticking these on the same sides of the graphic. I worked up a quick and simple example with the iris data : ### here's the basic graph

Hello R-helpers, I'm looking for a way to rename strips in lattice plots when I have more than one conditionning variable. Here's a dummy example taken from http://casoilresource.lawr.ucdavis.edu/drupal/node/510 library(lattice) f <- function(a, b, x) {p <- (exp(a + b*x)) / (1 + exp(a + b*x))} x.seq <- seq(-5, 5, by=0.5) x <- rep(x.seq, 9) a.seq <- c(-2, 0, 2) b.seq

Hi! Is there a way to manually costumize the color legend in an spplot() - especially where to draw ticks and labels for the ticks? The reason I'm asking: Usually spplot() automatically divides the data into fitting slices and makes a color legend (also automatically). I want to assign the slices myself and have a fixed scale instead of an automatic/dynamic scale. I think what I want gets

Soon on CRAN a new version of package gstat will emerge, which has a few minor changes and possible incompatibilities w.r.t. the previous version(s). The new gstat (0.9-23) now: + depends on sp, and uses internally with Spatial* classes from sp if data are provided in the old-fashoned way (as data.frame) + has a vignette to get you started with the classes in sp + defines krige as a generic;

I uploaded gstat 0.9-12 to CRAN, which has a few important changes: 1. Cokriging cross validation Cokriging cross validation is now possible with the function gstat.cv: you simply pass a multivariable gstat object, and cross validation is done for the first variable in the object. Optionally, secondary variable records at locations coinciding with the validation locations are removed. 2. Class

Hi, I am very new to R and I am trying to write KML files. I am running R-2.13.1 and I have the following packages: - AKIMA - RGDAL - RSAGA - SP I was trying to run the simple example that I found at the following web page: http://spatial-analyst.net/wiki/index.php?title=Export_maps_to_GE The lines that I can run are: data(meuse.grid)

The following came up when Roger Bivand and I discussed R's name spaces and overlap in packages, in the bus to the field trip during StatGIS, last Tuesday: If two packages create the same class, say "variogram", and both are loaded, then using a method for an object of class "variogram" cannot discriminate between them and will call the method in the package loaded last.

Hi! How does one change the background color of the map-panel in spplot()? Example: library(sp) data(meuse.grid) gridded(meuse.grid) = ~x+y spplot(meuse.grid, "part.a") How would I get another background-color for the map-panel (but not for the whole plot) here? Thank you! Marcel

Much like time, spatial locations are not likely to change for observed data. Still, R has no infrastructure or knowledge about spatial locations. Many packages that deal with spatial data in R use their own classes to deal with spatial data. On the workshop on spatial statistics software held during DSC2003 (organized by Roger Bivand), we decided that a base class that defines classes for

I was able to hack the code in the polspline package in order to change the plot.polymars function so that I can set the limits of my y-axis. However, I was only able to do this by entering plot.polymars in R, copying the code to Word, changing what I needed, and then pasting the new code in R to redefine the polt.polymars function. I was able to successfully change the function, but now I would

I have found two prior instances of this question in R-help, but I can't find the answer, and I'm giving up on mindless tinkering. http://tolstoy.newcastle.edu.au/R/help/03a/5994.html https://stat.ethz.ch/pipermail/r-help/2004-December/062259.html I must be able to pipe the poltting commands to stdin and receive the plot on stdout, with errors written to stderr, should any occur.

Hi, please help!! I've been trying to fit variogram models using the REML method in the gstat package. Every time the Windows GUI crashes. For example library(gstat) data(meuse) x <- variogram(zinc ~ 1, ~x + y, meuse) v <- vgm(140000, "Sph", 800, nug = 10000) plot(x, model = fit.variogram(x, model = v, fit.method=5)) Other fit methods are non problematic (eg. fit.method=7

Hi ALL, With the pakage gstat How can one create a grid of points as in the meuse.grid example, from measuring sites as in the Meuse example Thanks in advance!

Hello, This may sound crazy, but I have a large number of Multiplan data files I'm in the process of recuperating, and I'm hoping to avoid having to open them one by one to convert them into a modern, directly usable format. So I was wondering if someone somewhere had encountered this and maybe had a way to read Multiplan files in R, or, at least, a way to read SYLK files directly in R.

I have a spatialpixelsdataframe containing bathymetry data. Is it possible to save this as something similar to the meuse.grid so it can be loaded without having to run the spatial interpolation each time the script is called? I don't see a straightforward method in the sp documentation.

The project involves a "private" broadcast so setting up firewall rules and forwarding would be a problem ... I'm going to post the project proposal once I have it finished, since it is a really cool project. -----Original Message----- From: Steve Meuse [mailto:swave@mara.org] Sent: Thursday, February 20, 2003 9:19 AM To: icecast@xiph.org Subject: Re: [icecast] UDP Vs.

I'm hoping to use R for spatial analysis. In working through examples in Chapt. 4 of Applied Spatial Data Analysis with R I've come across the following error in trying to plot lines with the meuse data set. The text is verbatim from the book. > m.sl <- SpatialLines(list(Lines(list(Line(cc))))) Error in Lines(list(Line(cc))) : Single ID required What does "Single ID
