I'm trying to index the word "peter-bengtsson" (which is different from "peter" & "bengtsson" and is different from "peterbengtsson") and find it. To start with I'm trying to use a basic python script to get to grips with it. When I do this:: qp = xapian.QueryParser() stemmer = xapian.Stem("english") qp.set_stemmer(stemmer)

Hello, I am a relatively new R-user who has a lot to learn. I have a large dataset that is in the following dataframe format: red A B C green D blue E F Where red, green and blue are "species" names and A, B and C are observations (corresponding to DNA sequences). Each observation can only belong to one species. I would like to list the observations in one column, with the species

Full_Name: Henrik Bengtsson Version: 1.3.0 OS: Windows Me Submission from: (NULL) (216.175.122.171) I realized that the title of packages in the library index when they are in a bundle is the title of the bundle and not the package. It looks like the TITLE file, which apparently is used for generating the library index, takes the value of the bundle's title and not the package's title.

Thank you for the feedback and confirmations. Interesting to see that it's also reproducible on macOS expect for Spencer; that might indicate a difference in builds. BTW, my original post suggested that timeout error was for sure detected while running Sys.sleep(10). However, it could of course also be that it is only detected after it finishes. For troubleshooting, the

Thanks, this was what I expected. There is a desire to eliminate the usage of pairlist from user code, which suggests the alternative of allowing for function arguments to be stored in lists. That's a much deeper change though. On Wed, Oct 12, 2016 at 12:31 PM, Henrik Bengtsson <henrik.bengtsson at gmail.com> wrote: > Michael, thanks for this info. > > I've stumbled upon

I am surprised by this. Why does R not do this automatically? What is the case for keeping the DLL loaded after the package has been unloaded? What

Aaaah ... and argh - I should have better not to post R question at midnight, especially when I know it forks the process and it's not using threads. Brain meltdown. (So, we'll proceed trying to use pthreads in matrixStats also for Windows). Sorry for the noise and thanks Kasper.

Thanks I think you have both answered my question (reckon Ill go S3 on that). As an adjunct to this do you know what might be the best reference to the S4 methods current implementation. I have ordered the Chambers book "Programming with Data", and I have a short tutorial-- "S4 Classes in 15 pages, more or less". Have I missed any other useful resources? Stephen Henderson

Sorry for not reading carefully and thanks for confirming problem with Rscript too.

Hi Henrik, It would help to understand your use case for pairlists.

A solution is to have parallel:::.slaveRSOCK() attempt to connect multiple times before failing, e.g. makeSOCKmaster <- function(master, port, timeout, useXDR, maxTries = 10L, interval = 1.0) { port <- as.integer(port) for (i in seq_len(maxTries)) { con <- tryCatch({ socketConnection(master, port = port, blocking = TRUE,

**Maybe this bug needs to be understood further before applying the patch because patch is most likely also wrong** Because, from just looking at the expressions, I think neither the R 3.6.0 version: omittedSig <- omittedSig && (signature[omittedSig] != "missing") nor the patched version (I proposed): omittedSig <- omittedSig & (signature[omittedSig] !=

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

Great. For the record of this thread, I've submitted patch PR17391 (https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17391). I've patched it against the latest R-devel on the SVN, passes 'make check-all', and I've verified it works with the above tests. /Henrik On Fri, Mar 9, 2018 at 4:37 AM, <luke-tierney at uiowa.edu> wrote: > I'm happy to look at a

I am aware of one (unofficial) guide to style for R programming: http://www1.maths.lth.se/help/R/RCC/ from Henrik Bengtsson. Can anyone provide further pointers to good style? Views on Bengtsson's ideas would interest me as well.

On unix, unless event polling is enabled Sys.sleep just waits in a select() call (with a SIGINT handler in place) so the elapsed time isn't checked until after the select call is complete. Rstudio uses event polling, and in particular sets R_wait_usec to 10000, which means event and interrupt checks happen during a Sys.seep call. The R GUI on macOS doesn't seem to do this (but my lldb

Just following up on this old thread since matrixStats 0.53.0 is now out, which supports this use case: > x <- rep(TRUE, times = 2^31) > y <- sum(x) > y [1] NA Warning message: In sum(x) : integer overflow - use sum(as.numeric(.)) > y <- matrixStats::sum2(x, mode = "double") > y [1] 2147483648 > str(y) num 2.15e+09 No coercion is taking place, so the
