…and learned to love SweaveHow I stopped worrying about figure placement

It's doingthe working
and the thinkingthat wears
a fellow out
I have an ideaI want to explore it I explore my idea by writing a computer program
I write R codeI want to ensure my exploration is reproducible and comprehensible– I explore this idea using literate programming
I use Sweave to write both R code and commentary
I want to communicate my explorations I communicate my explorations by writing a journal article
I write the article according to the journal’s instructions for authorsI want to ensure others can reproduce and comprehend my explorations– I include the literate program as Supplementary Information– I use the Supplementary Information figures in the journal article
More thinking… less working…How to use Sweave to streamline data analysis and publication

Let’s walk through the key steps
Let’s start a new project in RStudio

Be sure to set the project
options…
… so as to use knitr to weave .Rnw
files
You could also set
knitr in the global options
You could also set

Uncheck this option
to keep .aux files
Now open a new Sweave (.Rnw) file…
Now open a new Sweave (.Rnw) file…
…for Supplement
ary Information
This gives you a
skeleton LaTeX file…
…add content …compile to
PDF…
…here’s the compilation
report…
…and here’s the resulting
Now add code to
execute on compilation
See the result?
Now add a “chunk” of
code…
…here’s the pretty-printed result
Here’s a “chunk” that runs silently
…here’s the silent result
Now here’s a plot that
prints immediately
See the result? Code
first, plot after
Here’s a plot in a
“floating” figure
The figure floats to the top of the
page
Look at the files created
on compilation
The .aux file holds labels
for cross-reference
Compilation also creates
figures…
…figures named after the chunks
Now let’s write that Nature paper…
…let’s call it JournalArticl
e
Now we play by Nature’s
format rules
…still, we can cross-reference
Suppl. Info.
…here’s a cross-
reference
…and figures
made in the Suppl. Info
