I have a panel dataset of countries for which in each year (from 1980 to 2020) I have a dummy on whether there was a conflict in that particular country and another dummy on whether there was a coup. Moreover, I have for each country the ID of the neighboring countries, which are the same in each year. What I need to do in R is to create a new dummy "Conflict_Coup_Neighbors" which takes value 1 if in a particular year there was a conflict or a coup in at least one of the neighbor countries. I guess it should be a loop that checks for each country, for each year and for each neighbor whether the dummy conflict or coup of the neighbor are =1 but I can't understand how to set it up. Below I leave a snapshot of the dataset Dateset
