CodeMark Gem

Ruby gem to convert RMarkdown (.Rmd) files to pure R scripts (.R)

• Strips out Rmd headers
• Converts Rmd regular text to R comments
  • Converts headers to comment, marking the header level
  • Wraps text to 80 chars/line and makes each line a comment
  • Converts horizontal rules to commented series of many dashes
• Converts Rmd code chunks to regular R code
  • Does not copy over non-echoed code (i.e., ignores echo={FALSE|false|F})

Execute in shell using:

codemark <filename.Rmd> 

CodeMark will produce a corresponding file called filename.R

There is only one test currently, and it ensures that fixtures are processed accurately (i.e., a given Rmd file is correctly converted into a given R file).

rake spec

If the R file is accurately produced, minitest helpfully shows line diffs between the fixture R file and the generated R script.

If you deliberately change the behavior of CodeMark so that it produces different R output, then you must update the R script fixture:

rake install      # builds and reinstalls codemark gem locally
cd spec/fixtures
codemark sem-intro.Rmd
