A question about capturing videos to a Samba share... When Apple's Final Cut Pro captures video files, it pre-allocates file space on the destination volume. If you capture to a local volume that's physically attached to a Macintosh, or if you capture to a network volume via AFP (Apple File Sharing Protocol), you can see that Final Cut instantly creates a file of the

>From the Details section of ?capture.output: Messages sent to stderr() (including those from message, warning and stop) are captured by type = "message". Note that this can be "unsafe" and should only be used with care. Capturing messages works as expected: capture.output(message("!!!"), type = "message") ## [1] "!!!" Capturing warnings doesn't seems to work: capture.outp...

In R-devel (2015-08-12 r69024), capture.output() incorrectly duplicates the last line unless it ends with a newline. I don't see this in R 3.2.2 RC (2015-08-13 r69049). It seems to have started fairily recently; I spotted this yesterday after starting to get errors in my R.utils check that use capture.output(), cf.

Hey Scott, There has been quite a lot of research on capture tracking (aka escape analysis) for Java and other dynamic languages. See e.g.: https://wiki.openjdk.java.net/display/HotSpot/EscapeAnalysis http://docs.oracle.com/javase/7/docs/technotes/guides/vm/performance-enhancements-7.html http://dl.acm.org/citation.cfm?doid=320384.320386 Nuno -----Original Message----- From: Scott Egerton via

Hello Anna, I've been looking into compiling a list of all of the false positives in the current Capture Tracking Analysis, but I'm having a bit of trouble getting my head around it all. I feel like I understand it at a theoretical level but jumping into the implementation is quite daunting. I would appreciate any advice you could give to point me in the right direction. Many thanks,

Hellow everybody, I have a dataframe with 468 individuals (rows) that I captured at least once during 28 visits (columns), it looks like: mortality[1:10,] X18.10.2004 X20.10.2004 X22.10.2004 X24.10.2004 X26.10.2004 X28.10.2004 X30.10.2004 X01.11.2004 X03.11.2004 X07.11.2004 1 1 0 0 0 1 1 1 0...

Full_Name: Philippe Grosjean Version: 2.6.1 OS: MacOS X; Windows XP Submission from: (NULL) (81.243.237.235) Last output from capture.output() is truncated if it does not end with a carriage return: > capture.output(cat("text\n")) # Fine [1] "text" > capture.output(cat("text")) # Missing output! character(0) >

This only happens if 'file' is a text connection, and is the expected behaviour in that case: you cannot capture an incomplete line to a text connection. There seems no reason to break the documented behaviour in other cases to change something that you consider to a bug when file=NULL and the user does not produce complete output. It would be possible to make use of isIncomplete()

Hi, I would like to know how to capture the console output from running an algorithm for further analysis. I can capture this using capture.output() but that yields a character vector. I would like to extract the actual numeric values. Here is an example of what I am trying to do. fr <- function(x) { ## Rosenbrock Banana function on.exit(print(f)) x1 <- x[1] x2 <- x[2]

Hi all, We all know that mismatch between clocks of ADCs of far-end voice and near-end voice is not allowed in a time-domain or frequency-domain LMS based AEC system. It means that capture and render audio streams must be synchronized to a same sample rate. However, I found that this restriction is removed in microsoft AEC from Windows XP SP1. Anyone knows how microsoft AEC do it? This technology

Is there any way to include warnings in the output from capture.output? eg: a <- capture.output(warning("test")) all.equal(a, "Warning message: \n test ") Conceptually, this seems like redirecting stderr to stdout, or somehow changing warning to simple print it's output. I've had a look at tryCatch and using a warning handler, but this terminates execution at the

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 <-

I want to capture all SIP messages. I have about 30 hosts in about 6 colos. My first thought was dumpcap, but the output file name format bugs me.

I've noticed the following oddity where capture.output() prevents eval() from evaluating an expression in the specified environment. I'm not sure if it is an undocumented feature or a bug. It caused me many hours of troubleshooting. By posting it here, it might save someone else from doing the same exercise. Start by defining foo() which evaluates an expression locally in a given

The fix for PR#16481 had a side effect involving capture.output(), so this may be transient, please recheck whether the issue has disappeared in the meantime. -pd On 14 Aug 2015, at 11:09 , Henrik Bengtsson <henrik.bengtsson at ucsf.edu> wrote: > In R-devel (2015-08-12 r69024), capture.output() incorrectly > duplicates the last line unless it ends with a newline.

...e cannot be controlled via install.packages. I'm a bit reluctant to start rolling my own version of install.packages just for this reason. Is there any way to somehow grab this output? Or alternatively, is there a way to make R pipe stdout and stderr from system2 in such a way that they can be captured with sink or capture.output in the R parent process?

Hi all, I have been looking at how to convert by-reference captures into by-copy captures for captured statements and possibly C++ lambdas, and am looking for some feedback on my approach. The motivation for trying to use copy captures is to avoid unnecessary loads that are otherwise required inside the outlined function. This can be important when the outlined function represents the body of a lo...
