View R function bodies as JSON Objects

fxn2json.R

## Once you've loaded the dependencies you don't have to load them again in a session 
## May have to install them via `install.packages(c('RJSONIO', 'plyr'))` first and only once per device
# Uses C parser for faster results compared to rjson
require('RJSONIO')
# Get a quick non-trivial function example
require('plyr')

# body(x) extracts the function body for x (also could set the function body of x)
ddBody <- as.list(body(ddply))

# Print the results. Could also stream them over a shiny server to a browser.
cat(toJSON(ddBody))
