Last year there was a request seeking functions to plot Venn diagrams in
R. Seeing no reply and for other reasons needing this, I wrote a quick
routine. The general problem of creating a Venn diagram with overlap
areas proportional to the number of counts in each overlap is over
determined. An

Hi,
When I use the function plot() to plot a categorical variable with two
levels versus a continuous variable, the two levels of the categorical
variable are plotted at the values of 1.0 and 2.0. I would like them to
be plotted at the values of 0.0 and 1.0. How can I do this?

Yes, but that relies on the internal representation of POSIXct objects,
which is probably unwise.

Hi
I've installed the "R" system under Solaris 8 on a SunFire V880. I
configured it using the "--with-x" option. Installation seemed to go
fine, but when I start R with the X-Windows GUI option,
R --gui=X11
I just get put into the command-line mode.
Any ideas what I'm missing?
