Thank you Erik!
That works nicely now. The file size in (in kilobytes) is equal to the
"File>Save As>PDF" method.
Still curious why the file sizes (in Kb), differ by a factor of ~2
between the two methods:
pdf()
dev2bitmap(method = "pdf")
I'm just *assuming* here that file size is inidcative of image quality.
Is this assumption correct? If so, how would one increase .pdf quality
within the dev2bitmap() function?
With thanks for any further thoughts on this, cheers,
Karl

The `pdf` function opens a *new* graphics device, you then send output
to the device before calling dev.off(), e.g.,
pdf(file = my_plot.pdf")
plot(1:10, 1:10)
dev.off()
-yields a .pdf file of 1kb (same plot example) and returns the
following error when attempting to open with Adobe acrobat:
"There was an error opening this document. This file cannot be opened
because it has no pages."
