Dear R devel list
I was wondering whether zip() contains a windows specific call to
system(),
Actually, it does not contain a call to system() ....
as the argument "invisible" seems to be windows specific, yet
is used anytime by zip:
And what is your problem here? R ignores the arguments to systems()
where not needed.
invisible(system2(zip, args, invisible = TRUE))
Indeed, calling zip() on Linux results in a warning message:
file.create("try")
[1] TRUE
zip("try.zip", "try")
adding: try (stored 0%)
Message d'avis :
In system2(zip, args, invisible = TRUE) :
arguments 'minimized' and 'invisible' are for Windows only
unlink("try")
