Dear R experts,
On shutting down a device with dev.off(), the number and name of the new active
device is returned/printed. How can this be prevented from being shown? Is
there something like a 'quiet'-mode?
Like any other expression, if you assign the result to a variable, it
won't be printed. So
x <- dev.off()
would work.
If you don't want to waste a variable name, you can achieve the
non-printing by wrapping the call in invisible():
invisible(dev.off())
will return the result with printing turned off.
