[R] [FORGED] Plotting in LaTeX with ggplot2 in R and using tikzdevice

[Ulrik Stervbo]

I saved my plots as pdf and used pdflatex. It's a few years ago and now you
can even use the r-package cowplot to create panels with subfigures. That
means more work with r, less manual work.

I believe kable from the knitr package can export tables for latex too.

Hope this helps.
