I am having a series of problems using date time data that has been converted into a POSIXt and POSIXlt classes. I have hourly time series data from 1900 that has been converted from text data. I assume most of my problems come from a mis-underdanding of the POSIX class. My matrix named (aa) for this year is approx 8700 by 4. When I try to calculate the length of posit column ( which is the

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, I am trying to take difference of two time objects. I want to fix the result's unit to minutes. How can I do that? Here is an example: > difftime(x, y) Time difference of 2.030720 hours > difftime(x, z) Time difference of 30.34672 mins where x = '2007-03-05 08:32:58' y = '2007-03-05 06:31:07' and z = '2007-03-05 08:02:37' How can I get answer

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!
