Hi all, While dat['a1',] and dat['a10',] produce the same results in the following example, I'd like dat['a1',] to return NAs. dat <- data.frame(x1 = paste(letters[1:5],10, sep=''), x2=rnorm(5)) rownames(dat) <- dat$x1 dat['a1',] dat['a10',] > sessionInfo() R version 2.7.2 (2008-08-25) i386-pc-mingw32 locale:

I am the maintainer of a Bioconductor package (affylmGUI) which uses tcltk. It freezes inconsistently on MS Windows, but not Mac or Unix. see details below. After considerable testing I have reduced the problem from a few thousand lines of code to 30 lines! If you paste the following lines of code into an R window: testGUI <- function(){ require(tcltk) MainWindow <-

I run R on MS Windows. In R2.9.0dev, I type ?base to get "R help for package base" to open. I then select ".First" from the list of contents, getting a page headed: "Initialization at Start of an R Session". About half way down there is a sentence: The command-line flag --vanilla implies --no-site-file, --no-init-file, --no-restore and --no-environ. Under

Hi all I have built a Bayesian network using discrete data using the bnlearn package. When I try to run the cpquery function on this data it returns NaN for some some cases. Running the cpquery in debug mode for such a case (n=10^5, method="lw") creates the following output: generated a grand total of 1e+05 samples. > event has a probability mass of 14982.37 out of

Good day, I'm trying the example cl <- makeCluster(2, type = "SOCK") from the makeCluster documentation and the R command prompt never returns. I am using a 32-bit Windows 10 computer. The problem doesn't happen on another 64-bit Windows 10 computer but does happen on another 32-bit Windows 7 computer. Can anyone reproduce it? Are there any other options that can be passed to

I get the same style of path as Hadley. This is on Windows 7 Home Premium with SP1. I start R by clicking on the R-2.31.0 icon. I'd assumed that it was a change that came with R-2.13.0!

Hi, I'm trying to write a function in C for implementation with .Call. When compiling using R CMD SHLIB characters seem to be added to the function name.

list(...) I can not get at the grid viewports in a ggplot2 plot. I know there is supposed to be a viewport called "panel_1_1" but downViewport() can't find it. Has the viewport been popped? I had a quick look at the functions involved (eg ggplot_plot) but there is no obvious problem there. > library(ggplot2) > qplot(1:10, 1:10) > current.viewport() viewport[ROOT] >

Hi list(...), I've narrowed down a weird bug. It's like a ghost in the machine, in that functions seem to remember things that they should not be able to. In the example below, the result of the second (and subseqent) calls depend on what was given in the first call. foo <- function(given = NULL) { callObj <- quote(callFunc()) if (!is.null(given)) callObj$given

Dear All I have a problem with the height of the boxes in the key in the following. (The text is over 2 lines to accentuate the problem of no space between the rectangles.)
