Converting Sweave/R plots for inclusion in Word/OpenOffice
Just a quick note to myself:
When you use Sweave and produce high-quality plots in both EPS and PDF formats, you sometimes want to include them in Word or OpenOffice documents.
You can’t directly include PDF files, and you can only include EPS files when they have a preview, which Sweave will not do by default. And anyway, the EPS version of the graphs are made for black and white printers and will not be in color.
I’m using convert from the ImageMagick package to convert the PDF plots to PNG files. However, by default convert will give low-quality pictures. To have better images, I do:
convert -density 300 XXX.pdf XXX.png
If you feel geeky enough you can even include this in a Makefile:
figures: $(patsubst %.pdf, %.png, $(wildcard report-*.pdf))
report-%.png : report-%.pdf
convert -density 300 $< $@
