[R] Bounding box on plotting files inserted into a LaTeX document

[Patrick Connolly]

I'm trying to write basic latex code to insert a pdf graphic into a
document.  I can use Rstudio to knit an Rmd file successfully
inserting the plot into the document.  I can get the latex code if the
"save tex" box is ticked, so I get the correct syntax used.  

I don't need all the fancy things that .Rmd files can handle.  I just
want a simple .tex file.  However, if I try to use a pdf file normally
produced by using the pdf device, I get a message about a missing
bounding box.  So I thought it might work to use R to make an eps
file, which pdflatex automatically converts to a pdf.  It does import
the graphic, but it takes up a whole page, which indicates that it
ignores the bounding box.

What does work is to use Rstudio interactively to export the graphic
to a pdf file which pdflatex handles correctly.  But that's a clunky
procedure which I'd like to avoid.  It must be possible since graphs
were included in LaTeX documents for decades before there was Rstudio.

TIA
