sweave tables as images?
you can open a device that has the exact dimensions of the table,
g = tableGrob(head(iris, 4))
png("test.png", width=convertWidth(grobWidth(g), "in", value=TRUE),
height=convertHeight(grobHeight(g), "in",
value=TRUE),units="in", res=150)
grid.draw(g)
dev.off()
Doing this with knitr might be tricky though, since the unit
conversion opens a blank device window, and you'd want to define some
hook instead of manually creating the png file.
I have another version of grid.table where you can specify the width
and height manually [*], e.g to span the full window, but it's not
necessarily a desirable thing (the spacing between rows and columns
can become too large).

Thanks Yihui, That's a great idea, and comes close to the mark, except that I have to use png's in order to "Insert & Link" them as pictures in Word (and hence make the doc both shareable and update when new figures are generated). thanks, allie On 5/25/2012 2:57 PM, Yihui Xie wrote:
You may take a look at knitr's graphics manual which tells you how you can automatically crop the white margins: https://github.com/downloads/yihui/knitr/knitr-graphics.pdf ("Cropping PDF Graphics"). I'm not sure if pdfcrop works in this case, though.

grid.table() works well, but using it in sweave creates graphics with very wide margins. ?I'm sure this has something to do with grid, and not just grid.table. ?Any idea how I can clip the graphic to the edges of the table graphic? ?I've looked into viewports, etc, but I can't seem to find anything that will clip a graphic to its edges, perhaps with some defined margin. any help greatly appreciated! thanks, allie
