FWIW I have a basic RVowpalWabbit pkg on CRAN. Needs some love as code is very cmdline centric. Help welcome. /cc @revodavid @rstudioapp

@hadleywickham For things I cannot assume (or which are expensive), I tend to mock the call using data in RData (or rds) files.

@romain_francois There are about a dozen packages by DTL in that space; maybe you can pick something useful up from them.
Replying to @romain_francois
Yes, Ben Bolker had suggested the same. Patches / pull requests welcome. RT @romain_francois @winston_chang @CRANPolicyWatch

@hadleywickham Well pull request away :) For Repo Policy, I use a svn rev counter at the top of file. Manuals do not have that. digest()?
Replying to @hadleywickham
@hadleywickham Work in progress. I may commit the txt variant at top-level as 'policy.txt', we'd see the diffs there. Suggestions welcome.
