The purpose of this package is to provide a way of visualizing code changes
between steps. The idea came from the difficulty in tracking what components of a
complex ggplot correspond to various settings. The functions in this package
provide the underlying infrastructure to diff between 'steps' to visualize
what things are changed similar to git diff.
The way the package works is to add an extra macro to Rmd document to declare what code chunks correspond to steps you want to visualize.
### Step 1 - <some description>
@start step1
``.`{r }
<some code>
``.`
@end step1
### Step 2 - <some description>
@start step2
``.`{r }
<some code> with some additional changes@end step2
`.
(dots in the rmd code chunks to fix rendering on github, but should not be present in real Rmd)
