I was extremely disappointed by this report. Unix/Linux R users should
appreciate what was ported from the Windows version for them and not send
a bug report on a well-documented restriction. Especially when the `See
Also' mentions an alternative!
The comment only applies to R on Unix/Linux, not to the original png
device on Windows. It ignores the bitmap() device which we also provide,
and the warnings in the help page, to wit:
R can be compiled without support for either or both of these
devices: this will be reported if you attempt to use them on a
system where they are not supported. They will not be
available if R has been started with `--gui=none' (and will give a
different error message).
Now, why send a bug report about something documented on the help page?
(And you need a X display for any other --gui option, including the
default.) Please do read the section in the R FAQ about what is a bug,
and act on it.

See the `See Also' on ?png!
