There seems to be a bug in "image" in R 13.1 (on windows 32 & 64 bits) and on R-devel that is not present in R 13.0 and before. The below creates a plot with many white lines, horizontal and vertical, more or less regularly spaced. The effect is particularly dramatic when the plotting window is made very small. image(t(volcano)[ncol(volcano):1,]) Robert Hijmans University of

I get an error when using self-defined (not standard) functions with mapply with S4 objects from the raster package that I develop: "Error in as.character(sys.call(sys.parent())[[1]]) : cannot coerce type 'closure' to vector of type 'character'". Does anyone understand why? The problem is illustrated below. Thanks, Robert > # First a general example that works

I had difficulties running R CMD check and build on windows 7. The problem seems to be that the script creates folders to which nobody has any access permissions (not even read). So the script can not delete these folders or open files. This worked for me: Go to the properties of the root folder of your R project (e.g. "D:\R"). Change the settings so that this folder and its

Hi, R-help, (sessionInfo at the end) I'm trying to construct a function using bquote and running into a strange error message. As an example, what I would like to do is this: z <- 2 eval(bquote(function(x, y) { x^.(z) + y }))(2, 3) However, I get the following: Error in eval(expr, envir, enclos) : invalid formal argument list for "function" However, if I change the

Hi, all, (sessionInfo at the end) I've been struggling with the tcltk package and can't seem to get the ttkcombobox to work. Here's an example: library(tcltk) p <- tktoplevel() l <- tclVar() ## I don't know if I'm even calling it correctly cb <- ttkcombobox(p, values = letters[1:4], textvariable = l) tkpack(cb) 1. How do I know when the value of the combobox has

When I type the following, I get results different from what I expected. > sprintf('%a',3) [1] "0x1.8" Shouldn't the result be [1] "0x1.8p+2" I read through the help ?sprintf and didn't find anything that changed my expectation.

I am trying to use winProgressBar, however I find that although setWinProgressBar updates the value on the screen, getWinProgressBar does not return this value. E.g > pb <- winProgressBar() > setWinProgressBar(pb, 0.2) > getWinProgressBar(pb) [1] 0 I tried the same with tkProgressBar, and it is working as I would expect from the documentation. > pb <- tkProgressBar() >

This is not a major issue, but is there any way to get the full directory name out when dir.create issues a warning? I am running R 2.8.0 patched on Windows Vista - full details below. With the following code: dir.create("test") obscure<-"test" dir.create(obscure) I get the warning message: In dir.create(obscure) : 't' already exists Session details: R

Hi R-list, I'll apologize in advance for (1) the wordiness of my note (not sure how to avoid it) and (2) any deficiencies on my part that lead to my difficulties. I have an application with several stages that is meant to simulate and explore different scenarios with respect to product sales (in units sold per month). My session info is at the bottom of this note. The steps include (1) an

Hi (Duncan?), The other day I noticed some characters will cause errors in R CMD CHECK because of parse_Rd(), and AFAIK, these chars include '%', '{' and '}'. For example, note the comments in the example section: %~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~% \name{testfun} \Rdversion{1.1} \alias{testfun} \title{ A Test } \description{ A test } \usage{ testfun() } \value{ NULL }

With floating point numbers I'm seeing 'cut' putting values in the wrong bands. An example below places 0.3 in (0.3,0.6] i.e. 0.3 > 0.3. > x = 1:5*.1 > x [1] 0.1 0.2 0.3 0.4 0.5 > cut(x, br=c(0,.3,.6)) [1] (0,0.3] (0,0.3] (0.3,0.6] (0.3,0.6] (0.3,0.6] Levels: (0,0.3] (0.3,0.6] I'm sure this is probably the same issue documented in the FAQ (7.31 Why doesn't R

I recently built R-devel on Windows XP (sessionInfo below), and when loading libraries that require the iconv.dll was getting an error stating that 'This application has failed to start because iconv.dll was not found. Re-installing the application may fix this problem.'. An R-2.8.1 that I installed using the Windows installer has this dll in R-2.8.1/bin, whereas in R-devel it is still in

Hi, I seem to be facing a strange problem when I use Sweave for creating a LaTeX document of the R lme() output --- The EPS and PDF figure files get created, but are empty.

Hi- I'm running Vista64 Business and trying to use a package called RGraphViz. Unfortunately, when I try to plot a graph using this package it causes RGUI.EXE to crash. This package has no problem working in WinXP 32-bit. Is there any way to get useful information as to why it crashes?
