render to pdf not including images (plots) on output

[leonsas]

So when trying to render an Rmd to pdf, the output goes through without inserting the figured in the pdf. When knitting to HTML, the plots do get included.

See this gist: https://gist.github.com/leonsas/308ec0bfaaaaa2701017 for all the output files. I couldn't figure out what it is, but I suspect its something with the paths to the generated figures.

I tracked this problem to the use of the fig.align chunk option (if you remove it then the plots appear in pdf output). @yihui I noted that this is documented to be the behavior of knitr:

fig.align: ('default'; character) alignment of figures in the output document (possible values are left, right and center; default is not to make any alignment adjustments); note that for Markdown output, forcing figure alignments will lead to the HTML tag instead of the original Markdown syntax , because Markdown does not have native support for figure alignments (see #611)

For situations where Rmd is not targeting HTML could knitr just ignore fig.align?

Yea, fig.align was the problem. I do think that knitr should ignore fig.align in such situations, since often times the Rmd is meant to be used both for pdf and HTML.

I'm saying ignore fig.align for PDF only (as opposed to omitting the images
entirely).

I think I have a better idea to solve this problem (i.e. use raw_tex for plots when the pandoc output is pdf). I'll experiment with it and let you know.

@yihui Closing this issue here (assuming that you are tracking the possible raw_tex enhancement in the knitr issues database)

FYI: This has been fixed in the development version of knitr, which I plan to release to CRAN in the next few days.
