Subject: r-base: png output requires X connection

Date: Wed, 10 Oct 2001 13:40:06 -0700
Package: r-base
Version: 1.3.1-2
Severity: wishlist
R doesn't allow use of png() without an X display. It would be great for
automated graph generation if an X display were not required. While one can
workaround this by using postscript() and the png output of ghostscript, the
output does not look as good as R using the png() device directly.

[Rd] png output requires X connection (PR#1165)
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.

Anyhow you can turn it off and get sharp, clear output from ghostscript. I agree it would be nice if the PNG output was not directly tied to the GUI but there are plenty of ways to get around the problem. - Tel -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the "body", not the subject !)
