[R] Tracking when an object/function was modified

[Mona Kanaan]

Dear R-users,

If I would like to track the date when an R-object (specifically  an R- 
function) was modified, how can I achieve that? Furthermore, how can I 
sort these objects based on date  modified?


Your help is greatly appreciated
All the best

Mona
