How can I eliminate the border drawn by default around a wireframe plot? I've tried using border=NA and box=FALSE to no avail. Scott Waichler Pacific Northwest National Laboratory scott.waichler at pnl.gov

Hi, Does anyone have an example of making a map figure with an inset, where a portion of the map in the large figure is shown at a larger scale in the inset? Scott Waichler Hydrology Group Pacific Northwest National...

Is there a way to get the aspect ratio as output from a plot() call or something similar in the base graphics system? I would like to note vertical exaggeration on an elevation profile. Thanks, Scott Waichler Pacific Northwest National...

Hi, Does an R function exist to convert to and from the State Plane Coordinates system used in the U.S.? My search with Rseek was fruitless. Scott Waichler Hydrology Group, Energy & Environment Directorate Pacific Northwest National Laboratory Richland, WA...

I see that R 2.9.0 *.rpms have been compiled for RH EL5, i386 and x86_64, and also for EL4 x86_64, but not for EL4 i386. Is this an oversight or will that version no longer be...

I can't find a way to change just the panel background color in lattice. I would like NA regions in levelplot() to appear black. I've tried the trellis.par.set() stuff, but it it makes the background of...

Hi, I want to apply a custom function to all the elements of one matrix. The function uses the value in the same i,j in a second matrix. How can I use apply() or similar function to avoid nested...

I'd like to have an Emacs keystroke that would let me toggle between T and F when editing logical settings in R code. I looked in the ESS documentation and in my O'Reilly emacs books but found nothing...

Is there an existing function to compute the coordinates for the center of mass of a variable in a 2D or 3D grid, where dx, dy, and dz are known for all cells? The mass in each cell varies by...

I have a 3D field of a scalar variable (x, y, z, value). Is there a way to generate a vector field from this data--gradient at defined points? I found the rasterVis package for 2D data, but as yet...

There's already an announcement about R 2.8.0, and yet there are still no R-2.7.2 binaries (rpms) for Redhat Enterprise Linux 4 and 5. Can the usual responsible party get on it? Can the system...

I can't find a way to control the distance between tick marks and tick labels in lattice. In a stripplot I'm making these components are too close. I don't see anything like base graphics mgp in the...

I am looking for a method that would determine whether any part of a line segment defined by (x0, y0) and (x1, y1) intersects a given polygon (true or false). I don't have any other geospatial needs here, so...

R-2.2.1 is still not available for Redhat Linux as an RPM on CRAN. It is available as an SRPM. Can someone fill me in on why it takes so long to make RPMs available? I would be...

Sander, >has anybody made an attempt to create the soil texture triangle >graph in R? See ternaryplot() in package vcd. Its options are quite limited, but it may help. I think you'll need to write your own function to...

When I use panel.contourplot() with filled color regions, the coloring follows the stair-step edge of the underlying grid instead the smooth contour lines themselves. How can I get the latter behavior? I would guess there is a much...

My newly installed R-2.1.0 apparently doesn't like forward slashes in filenames: > R.version.string [1] "R version 2.1.0, 2005-04-18" > plotfile <- "\home\mean_monthly_stl.eps" > postscript(plotfile) > plotfile <- "/home/mean_monthly_stl...

Hi, I am using levelplot() to plot a primary response surface, z1. I wish to write a custom panel function that will let me plot another surface z2 = f(x,y) over z1. The second surface z2 is either NA...
