Dear all, I am curious whether one can automatically update, say, a column in R, similar to how spreadsheets (Excel, etc.) do? In my specific case I have two columns with logical data, which individually convey different information, although ultimately for a common purpose (flagging for removal). I would thus need a third logical variable that would take TRUE if any of the prev. columns take value TRUE for the given line. Without using RExcel, would there be a way of automatising this (by "manual" I understand running some code to recreate the third variable prior to printing it)?
To R purists: I am not sure that this would amount to good programming habits. Also, this way of thinking comes from my infancy with Excel; should there be a better approach, please let me know.
