similar to: R 2.12.0 for Windows: error when loading (some) packages

Dear all, I've just downloaded R.12.0 from CRAN (http://cran.r-project.org/bin/windows/base/release.htm). I am unable to find RGUI.exe as well as Rterm.exe. Conversely to what is explained in readme.R.2.12.0: There are two versions of the R executable in R-2.12.0\bin\i386 (32-bit) or R-2.12.0\bin\x64 (64-bit). I can't find directories i386 or x64 in R-2.12.0\bin -- Renaud Lancelot EDEN

Dear all, When I use the cacheSweave package together with the Sweave option keep.source = TRUE, all the LaTeX code before the Sweave code chunk is included in the TeX file to be compiled.

windows XP R 2.8.1 I would like to learn to use Sweave with R. I have no experience using Latex. I have looked at the sweave manual (http://www.statistik.lmu.de/~leisch/Sweave/Sweave-manual.pdf) and have found it difficult to understand, probably because I don't know Latex. Can someone recommend a document that will get me started with Sweave? Thanks John Confidentiality Statement: This

I wonder why the following code does not produce filled points in the key, as I would have expected: > library(lattice) > x <- 1:10 > y <- rnorm(10) > xyplot(y ~ x, pch = 21, col = "black", fill = "grey", + key = list(space = "top", + text = list("data"), + points = list(pch = 21, col =

Dear all, I just installed R 2.5.0alpha and noticed new warnings related to the extractor "$" when using contributed packages. For instance: > library(RODBC) Warning message: $ operator is not valid for atomic vectors, returning NULL > library(aod) Package aod, version 1.1-18 > data(orob2) > m1 <- betabin(cbind(y, n-y) ~ 1, random = ~ 1, data = orob2) >

thanks a lot Renaud. but i was interested in Finney's fiducial confidence intervals of LD50 so to obtain comparable results with SPSS. But your reply leads me to the next question: does anybody know what is the best method (asymptotic, bootstrap etc.) for calculating confidence intervals of LD50? i could "get rid" of Finney's fiducial confidence intervals but

Dear all, I have computed a digital terrain model from a set of points (x, y, z) using the function interp() in package akima. I want to predict flooded surfaces given target values of z. I can display the flooded surfaces with contour() or image(), but I don't know how to get the polygons delimiting the surfaces. Did anyone write a function for this purpose ? Best regards, Renaud --

Dear R-Helpers, Is there a way to draw shaded (filled) polygons in panel graphs produced by xyplot ? I made different trials (see below) with polygon() and grid.polygon() but polygons are not drawn (probably for the same reason that prevents the use of lines, points, etc. in xyplot panels).

Dear all, 1. How can I compute the intersecting area between 2 polygons ? 2. I have polygons with coordinates in decimal degrees (i.e. 13 deg 30 min = 13.5 decimal degrees). I want to compute their area and get the results in square meters or square kiometers. Can anyone give me a conversion coefficient or a pointer where I can find this information (sorry for this off topic question) ? Thanks

Dear R-Users, I have a data frame with several categorical variables. I want to create a new data frame with dummy variables (with all levels).
