Re: [R] HOW TO FILTER DATA

Hello, If you want to select rows with just one IPC, use `==`. If you want to select rows with several IPC's, use `%in%`. See the code below for the two ways of doing this. oecd <- read.table(text = " Appln_id|Prio_Year|App_year|IPC 1|1999|2000|H04Q007/32 1|1999|2000|G06K019/077
