I\'ve included a library called blotter in my R script which has a bug in it. Is there an easy way for me to edit the source to try and debug the issue?
Your question of Is there an easy way for me to edit the source to try and debug the issue? has the obvious answer: Use the source, Luke!
blotter is a package on R-Forge from where you can get blotter sources here. That is the standard way of looking at Open Source and possibly helping it along with a bug fix.
