In R, is it possible to redirect console output to a variable? -


in r, i'm wondering if it's possible temporarily redirect output of console variable?

p.s. there few examples on web on how use sink() redirect output filename, none find showing how redirect variable.

p.p.s. reason useful, in practice, need print out portion of default console output of built in functions in r.

i believe results <- capture.output(...) need (i.e. using default file=null argument). sink(textconnection("results")); ...; sink() should work well, ?capture.output says, capture.output() is:

related ‘sink’ in same way ‘with’ related ‘attach’.

... suggests capture.output() better since more contained (i.e. don't have remember terminate sink()).

if want send output of multiple statements variable can wrap them in curly brackets {}, if block sufficiently complex might better use sink() (or make code more modular wrapping in functions).

linux - Does gcc have any options to add version info in ELF binary file? -

i mean whether gcc can insert source code version infor elf binary section or similar. not want change source file, add info gcc option in makefile. you can emit version info text file, turn text file object file statically link executable. the first step simple have write code: script or write version info in format plain text file. write makefile rule produce version.o version.txt, using objcopy . you'll have object file 2 useful symbols defined in it: beginning , end of textual version info. add generated object executable, , you'll able access version 2 ways: running strings on binary, or writing code in application print version string (you'll need declare start , end symbols variables in header file).
