Hi everybody I couldn't find the solution to what must be quite a simple problem. Maybe you can help?
treatment session period stage wage_accepted market 1 1 1 1 1 25 public 2 1 1 1 1 19 privat 3 1 1 1 1 15 public 4 1 1 1 2 32 public 5 1 1 1 2 13 privat >From this table, I'd like to choose only those values in the column "wage_accepted" that have the value "public" in the column "market". How can I do this? Is there a good general help site for R that would explain basic table manipulations such as this?
