Dear all,

I am writing my Master's Thesis and am currently cleaning my data. For each Company I want to delete observations if they lie within 5 days of other observations of the same Company (-5, +5). See below a small snapshot of my database. Any thoughts on how to handle this the most convenient way? Thanks!
