Hello,

Is there a way to drop observations using a list of IDs ? I have a dataset and there are several observations (about 20k) I need to drop. I have the ID of these observations but they are too long to paste in the command.

To give the context of this issue, I have two datasets, one of firms with different segments and one of all firms, I want to remove all multi-segment firms and get a dataset of only firms operating in only one industry segment.

Any advice is greatly appreciated! Thank you
