Dear R Gurus, for some purpose i have to use a socket connection, where i have to read and write both text and binary data (each binary data package will be preceeded by a header line). When experimenting, i encountered some problems (with R-2.0.1 under different Linuxes (SuSE and Gentoo)). Since the default mode for socket connections is non-blocking, i first tried socketSelect() in order to

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. In R master session > con <- socketConnection('localhost', port

I'm trying to use snow in my dual-core (hopefully later this is going to run in a cluster). So, at this moment I create a cluster using SOCK connection (MPI in the future). However when I try to use clusterApplyLB I got "Error in socketSelect(socklist) : not a socket connection". Any ideas ? Do you know if that is going to be an isuue too when I swith from SOCK to MPI ? Sample code

Hi, After returning home from holiday I tried to update my Fedora installation with the command 'sudo dnf update -y'. This command now terminates with the following error: error: Verifying a signature using certificate 3124D2EF76DA4D972F6BE4AC9D60CBB71A3B4456 (iucar_cran (None) <iucar#cran at copr.fedorahosted.org>): 1.

R Gurus / Ninjas / Wizards: On both R 2.12 (Windows 7) and R 2.13 (OS X 10.5) I have tried the following: 1. In one instance of R open a socket via: s1 <- socketConnection(server=TRUE, open="a+b", port=31415, blocking=FALSE); 2. And in another instance I do the following: s2 <- socketConnection(open="a+b", port=31415, blocking=FALSE); And so I

I'd like to follow up/bump the attention to this bug causing the timeout to fail for socketSelect() on Unix. It is still there in R 3.4.2 and R-devel. I've identified the bug in the R source code - the bug is due to floating-point precisions and comparison using >=.

Dear reader, I am having problems getting new mail into my Inbox. I have this in my dovecot.conf: default_mail_env = maildir:~/Maildir:INBOX=/var/mail/%u The logs show nothing special, catting /var/mail/%u shows the new mails coming in, as does /var/log/mail.info Any clues?

I am writing a function to make a multi-part form request with binary data. I am running R 1.8.1 on Linux ReadHat. The sockectConnection is initialized with open="a+b" and blocking=TRUE. After writing the Post request using writeChar and writeBin and flushing the connection I use socketSelect to check if the socketConnection is availabe for reading. This call consistently takes 15

My followup question went unanswered in another thread, so I thought I'd start a new one and rephrase it. I need to use CGI POST to retrieve data from a server, so thanks to Duncan's suggestion, I used the httpRequest package as example code for doing so. BUT, I have another problem. The data retrieved from the socket has occasional problems. I include example code below to

Hi I have noticed that asterisk returns 'SIP 603' when the called party does not answer. My test setup is simple: two SIP phones (extensions: 100 and 111) registered to an Asterisk 1.8.30.0 gateway.The Dial timeout is 30 seconds. When 100 calls 111 and after 30 seconds, asterisk sends a CANCEL request to 111 (expected) and a '603 Decline' response to 100 (unexpected &

The wiki page for the feature matrix [1] has been gone for weeks, yet it is still being linked to from the nouveau main page [2]. Personally, I'm sad that it's gone. Will it come back eventually?

Hello R people, I have created a '.csv' file of 100 rows by 20 columns whose each cell contains a random numbers between 0 & 1, thru a Java program. Once that is created a signal (just a letter) is send to the port of a socket connection at "localhost", which was earlier started by an "R" session. Now the "R" reads the '.csv' file into a data

Dear Yihui, Thanks a lot for your help! Unfortunately, I was not able to reproduce this. I've tried creating files with Chinese characters in their names and populating them with valid UTF-8 and valid non-UTF-8 text, but R seems to be able to list them all in my case. I'm running a US English evaluation ISO image of a slightly newer build of Windows 10, and I also compiled R-4.3.1 from

Yes, I participated in the discussion. Basically dir() failed to list all files since R 4.3.0 when filenames start with Chinese characters. I don't have a Windows machine to test it, but this might be a minimal reproducible example: file.create("????.R") dir() The OP said dir() would return "????.R" in R.4.2.2 but not in R 4.3.0. In the same discussion another person
