Hello, I am using function makePSOCKcluster to make parallel computation on 3 EC2 Amazon machines. I have a passwordless between machines and ssh is correct. In the R 2.15.1 release this function works correctly. Installing R 3.0.1 on my EC2 machines makePSOCKcluster does not produce the cluster. If I run the function with outfile="" option, I obtain this message Error in

BACKGROUND: While troubleshooting random, occasionally occurring, errors from parallel::makePSOCKcluster("localhost", port = 11000); Error in socketConnection("localhost", port = port, server = TRUE, blocking = TRUE, : cannot open the connection I had another look at parallel:::newPSOCKnode(), which is used internally to set up each background worker. It is designed to,

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,

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

(Bcc: CRAN) This is a proposal helping CRAN and alike as well as individual developers to avoid stray R processes being left behind that might be produced when an example or a package test fails to set up a parallel::makeCluster(). ISSUE If a package test sets up a PSOCK cluster and then the master process dies for one reason or the other, the PSOCK worker processes will remain running for 30

Hi, I have trying to run a simple MR program using rmr2 in a single node Hadoop cluster.

Dear All, I had done an automatic upgrade of my Debian 10 system which had also upgraded R. I reinstalled the stargazer package and the error went away.

I just noticed that parallel:::.slaveRSOCK() passes 'timeout' to socketConnection() as a character, i.e. there's a missing timeout <- as.integer(timeout), cf. port <- as.integer(port) and useXDR <- as.logical(value): > parallel:::.slaveRSOCK function () { makeSOCKmaster <- function(master, port, timeout, useXDR) { port <- as.integer(port) con

I need your kind help regarding the following: I wish to know is there any way to use R in Visual Basic environment. I want to develop a VB application where R can be embedded (R will work as a back end statistical engine). If available, please provide me some source of study materials/articles available on the internet related to this. -- Thanks & Regards, Soumen Pal [[alternative HTML

hey friends, I am using wine 0.9.12 on centos 4.0 kernel version is 2.6.9-34.0.1.EL. Whenever I try to run any application through wine I get the below warning and the application does not run. Langauge settings before were Indian English but later on I changed it to US_English but still I am getting the below error. Warning: Language 'en_IN' was not recognized, defaulting to

I'm happy to look at a patch that does this. I'd start with a small interval and increase it by 50%, say, on each try wit a max retry time limit. This isn't eliminating the problem,only reducing the probability, but still worth it. I had considered doing something like this but it didn't seem necessary at the time. You don't want to retry indefinitely since the connection

Hi, I am a beginner in R. I have a query as below: Is it possible to develop a Windows based statistical software (user-friendly) like SPSS using R as a programming language? Otherwise, is it possible to use R code directly (no command-line execution) in Windows based programming language such as Visual Basic? Please help me, if possible, with some link to study materials related to such topic.

Platform: Windows Version: 1.6.2 When first called, socketConnection gives an error. On subsequent calls it performs correctly. Thus the first call has the effect of "priming" the connection.

There's something weird going on for certain non-integer values of argument 'timeout' to base::socketSelect(). For such values, there is no timeout and you effectively end up with an infinite timeout. I can reproduce this on R 3.3.1 on Ubuntu 16.04 and RedHat 6.6, but not on Windows (via Linux Wine). # 1.
