similar to: numerical issue in contour.default?

I have carried out a spatial interpolation (Kriging) using surf.gls() The contour plot looks very plausible and the image plot is o.k too. The problem is, hovever, that I need the vectorized isoplethes, as in contour(). Unfortunately, I found no solution to get the internal data from contour(). Is there a possibility to extract contour lines as x-y-polygon from a grid without hacking plot3d.c?

Dear R developers, I've got an information from Prof. Ripley regarding a bug found with AdressSanitizer in one of our packages. It is now fixed, thank you for this information. Now, I would like to run AddressSanitizer myself before submitting the patched package to CRAN. Is there a recommendation of a suitable Linux distribution with gcc 4.8, ideally an ISO image or (even better) a

Hello, I want to do simulations with an external simulation model. For this purpose I wrote a R-script which makes the pre- and post-processing of the data (generate scenarios, analyze results). The R-script writes the input file for the simulation with e.g. write(x, file="test.dat", ncolumns=10) The problem is, however, that this command (and even constructions with cat) will add a

Hi all, we found, that R is not only *the* superior data analysis, graphics and statistics package, but it is also a general tool for implementing, running and teaching ecological models. Last week we held our second course "Modelling in Limnology" using R. Some material (code and docs) was produced for this purpose and may be interesting to someone else, so I put the tutorial

Hi all, I'm trying to make multiple lattice contour plots which have the same color key, to allow good comparisons. However, I run into some problems when fitting the plots to the color key. Basically my strategy to tackle this problem was: 1) define a color key for all plots; 2) calculate the variable range for each plot; 3) calculate the range of colors from the color key that correspond

Hi, I have the same problem and, at a first look, the issues reported by the CRAN checks seemed easy to fix. However, after checking it again locally and on http://win-builder.r-project.org it appeared that GCC 4.9.3 (Windows, Rtools 3.4), same also on win-builder reports even more issues, especially legacy Fortran (mainly Roger's #2 and #3), but also "warning: ISO C forbids

Hi, The R CMD check is successful in R 3.0.1 but fails to install package lmerTest under R-devel r63910, Here is what I get: ** preparing package for lazy loading Error in reconcilePropertiesAndPrototype(name, slots, prototype, superClasses, : no definition was found for superclass "merMod" in the specification of class "merModLmerTest" In DESCRIPTION file I have:

I have a problem, that the plot of mathematical formula sometimes crashes R on Linux (SuSE 6.2 and 7.0 on a Dual PIII/500 machine with 1GB RAM). The problem occurs for example in demo("graphics"), i.e. in the last part were the mathematical symbols are plotted. There are several circumstances to reproduce this segmentation fault, but the following is one of the most simple examples. The

Hello, I used the following codes to generate bivariate normal dependence structure with unit Frechet margins. Sigma <- matrix(c(1,.5*sqrt(1),.5*sqrt(1),1),2,2) # generate y <- mvrnorm(Nsam, c(0,0), Sigma) # random v <- cbind(pnorm(y[,1],mean = 0, sd = 1), pnorm(y[,2],mean = 0, sd = 1)) z <- cbind(-1/log(v[,1]),-1/log(v[,2])) z1 <- z[,1] z2 <- z[,2] And to

Hello, I'm almost positive R can do the following, I just haven't hit upon the right package or search terms, however. Here's what I'm after: I've got concentration output from two different models that I want to qualitatively compare in a contour plot (or some variant of a contour plot). The problem as I see it is that the data is not gridded is the usual regular fashion,

Hi, I am almost new to R. Would any one show me (please include an example) how to clip a contour or image figure so that I only see the image or lines inside a selected area?

Dear R help contributors, I'd like to plot ground temperature with time on X-axis and depth on Y-axis on this datasets ( http://r.789695.n4.nabble.com/file/n3301033/NEdaily.csv NEdaily.csv ), and to do so I use the following commands: library(RSEIS) xNE <- seq(1, as.numeric(as.Date(max(NEdaily[[1]])) - as.Date(min(NEdaily[[1]]))), 1) yNE <- rev(c(-0.3, -0.5, -0.7, -0.9, -1.1,

Hi all, I'm trying to generate a grid of four plots. The first 2 appear just fine, but the final 2 will not appear in the grid, instead overwriting the first two. Any ideas on how to get them all in the same window would be greatly appreciated.

Dear developers, I have come across a (somewhat strange) change in the encoding of Sweave output from R-2.9.2pat to R-2.10.0beta (apparently specific to Rgui) on Windows installations. Of course, the NEWS file contains quite a few changes concerning encoding, but I was not able to locate an entry which explains the observed behaviour. I am not very familiar with encodings/locales/codepages,

Dear list, I have a balance connected to the serial port of a windows machine ("COM1") and I read the text output of the balance with scan("COM1", what="character", sep="\n", n=1) after calling the previous line I press the print key on the balance which triggers sending one line of text to the serial connection and with R 2.9.2 I get something like Read
