In general, Sweave is making great looking PDFs for me.

However, when I plot a histogram, it is not appearing in my PDF.

I have a bare bones Sweave document as follows. I can't seem to isolate what is missing!

\documentclass{article}
\usepackage{listings}

\begin{document}
\SweaveOpts{concordance=TRUE}

<<ReadOrder,tidy=TRUE,highlight=FALSE>>=

p <- ggplot(diamonds, aes(x=carat))
p <- p + geom_histogram()
p
@

(PS : yes, I have the 'listings' package installed in my LaTex package! And yes, the plot is being printed to the terminal.)

Thanks in advance for any advice.

  • I provide small working examples with Sweave here for interested. – hhh Sep 30 '18 at 16:12

(Upgraded from a comment).

Try adding fig=TRUE in the chunk options. (You might need an explicit print() around the p in the last line of the chunk too ...) If you use knitr::knit instead of Sweave, you won't need either of those explicit specifications ...

  • This did the trick. The addition of the fig=TRUE into the chunk options worked perfectly. Thank you! – tumultous_rooster Sep 25 '13 at 23:23
  • @MattO'Brien apparently you are using the chunk options of knitr instead of Sweave – Yihui Xie Sep 26 '13 at 1:43
  • I cannot get any plots with Sweave with this example, only gibberish like here, ideas? – hhh Sep 30 '18 at 15:29
