similar to: input equivalent of capture.output

I am not sure if `pipe()` works for this, but if it turns out that it does not, then you can use the processx package, e.g.: > p <- processx::process$new("sed", c("-l", "s/a/x/g"), stdin = "|", stdout = "|") > p$write_input("foobar\n") > p$read_output() [1] "foobxr\n" The `-l` sed flag is to make sed line-buffered,

I suspect the reason for the seek is this: cat("1\n", file = "foobar") f <- file("foobar", blocking = FALSE, open = "r") readLines(f) #> [1] "1" cat("2\n", file = "foobar", append = TRUE) readLines(f) #> [1] "2" cat("3\n", file = "foobar", append = TRUE) readLines(f) #> [1]

HISTORY --- 2.3.3: - fixed bug in updater related to io files (see tmp_stdin in jobqueue.rb) - [IMPORTANT] removed feature where stdin jobs could contain comments (''#''). input lines are now taken literally __except__ blank lines, which are still ignored. - added ability to dump stdin/stdout/stderr for any job rq q stdout 42

Hi, I was wondering if there is anything more efficient than split to do the kind of conversion in the subject. If I create a data frame as in system.time({fd = data.frame(x=1:2000, y = rnorm(2000), id = paste("x", 1:2000, sep =""))}) user system elapsed 0.004 0.000 0.004 and then I try to split it > system.time(split(fd, 1:nrow(fd))) user system elapsed

Hello list: I am using R through Geany in Ubuntu.  The way i have Geany configured is that upon invoking the exectute command, Geany does a "R <myscript.R >myscript.out", thus getting all input from the myscript.R file and redirecting all output to the myscript.out file. This is a problem when I want to read, say a numeric value, from the keyboard, or when i'd like to output

Hi, sorry if this question is trivial or unclear, this is my first venture into mixed C/R programming (I am reasonably experienced in each separately). I am trying to write a serialization function for a format called typedbytes, which is used as an interchange format in Hadoop circles. Since I would need to serialize according to the internal R format many small R objects I looked at the c

hi. i'd like to instantiate sed(1), send it some input, and retrieve its output, all via pipes (rather than an intermediate file). my sense from pipe and looking at the sources (sys-unix.c) is that is not possible. is that true? are there any thoughts of providing such a facility? cheers, Greg

My ISP supports connections via ssh. I was using OpenSSH 1.2.3 (portable) on Solaris 2.5.1 (with EGD), and I could connect to my ISP just fine. They're using the proprietary sshd version 1.2.26 as far as I can tell. A connect session looks like: $ ssh-1.2.3 -v -l foobar xx.xx.xx.xx SSH Version OpenSSH-1.2.3, protocol version 1.5. Compiled with SSL. debug: ssh_connect: getuid 390

Andreas, How right you are! Still, I find it curious that in the context of the while(TRUE) loop, I am allowed to do this 653 times, with failure on the 654th attempt. Perhaps there is something asynchronous going on? If I eliminate the looping, it does indeed fail (as expected) on the first attempt to close the pipe.

I'm curious about this. I'm trying to reverse-engineer a really neato-device that hooks up to the serial port and has Windows software. I've figured out the protocol the device sends; I'm just not sure how the device is initialized. So I'd love to capture the Windows software doing the dirty deed.. and WINE is IMHO just the tool. So, question is: How do you capture serial

Dear R core developers, One feature from Python that I have been wanting in R is the ability to capture groups in regular expressions using names. Consider the following example in R. > notables <- c(" Ben Franklin and Jefferson Davis","\tMillard Fillmore") > name.rex <- "(?<first>[A-Z][a-z]+) (?<last>[A-Z][a-z]+)" > (parsed <-

Hi Benjamin, you cannot pipe to echo, since it does not read from stdin. echo just echos is first arg, i.e. echo /dev/stdin > /dev/null will echo the string "/dev/stdin"to /dev/stdout, which is redirected to /dev/null. Try p <- pipe("cat > /dev/null", open = "w") instead. Regards, Andreas 2019-12-06 02:46 GMT+01:00 Benjamin Tyner<btyner at
