After doing html slides what’s next?
Beamer is a LaTeX class for creating slides for presentations.
But I know nothing about Beamer neither about LaTeX.\
I wanted to convert the html presentations to Beamer, because the output of Beamer/LaTex is pdf, and pdfs shows nicely in figshare.\
Ok, pandoc comes to rescue us, I already have the files I’ve done with Rstudio and knitr which I described in the previous post so it’s very easy, with pandoc you can generate html slides or Beamer slides:
pandoc -t beamer RAE2012_DivPatron_charla.md -V theme:Warsaw -o RAE2012\_DivPatron\_charla.pdf
but the result is not very good, the images were BIG, very BIG.\ \ Thanks to Jeromy Anglim’s post about Beamer/Markdown I learn to use some simple LaTex formating commands for images:\
The problem is that images dynamically generated with R, can’t be formated this way. Knitr chunk options have the posibility to change size:
fig.height. The images get smaller but the fonts dont’ change it’s size, the images are awfull. The other chunk options to control output size:
out.height didn’t work with Beamer.
Thus I choose the option to modify the Markdown file generated by knitr with the previous LaTex command. It was not a very elegant solution but worked.
UPDATE: here there is a python script to replace
<center>!(figure)</center> with LaTeX code gist
Then I ended with two files: the Rstudio markdown with all the R commands to generate the plots and a modified markdown file used for generate the beamer output by pandoc.
And I uploaded the presentation to figshare, the presentation can be showed in your blog/web page using the code provided by figshare, it works!
I like the slides generated by pandoc/Beamer, so I think that I am prepared to say goodbye to powerpoint/impress now.
