[R] How to vectorize plot graphic?

[Alexander Shenkin]

Thanks Jeff.  I'm not sure to which manual you are referring.  Nothing
like what you mention is found here:
http://cran.r-project.org/manuals.html .  Perhaps you're referring to
The Data Import/Export Manual, but that wouldn't make sense.  Googling
"R Input/Output manual" doesn't help.

Regarding the device, I'm in R-Studio, plotting to the standard device
there (I suppose).  In any case, I'm not totally sure what the interface
between R-Studio's plot window and the R instance is.  I think that, as
you say, what I'm getting is as expected.  I zoom and the plot zooms as
expected.  So, I guess that part is solved.  However, the writing to
.wmf as a bitmap instead of a vector is still a mystery to me.

Thanks,
Allie
