HOW TO FILTER DATA
...nybody guide me doing it, also the IPC codes are string variables. The data is somewhat like below, but its a huge dataset containing more than 11 million rows Appln_id|Prio_Year|App_year|IPC 1|1999|2000|H04Q007/32 1|1999|2000|G06K019/077 1|1999|2000|H01R012/18 1|1999|2000|G06K017/00 1|1999|2000|H04M001/2745 1|1999|2000|G06K007/00 1|1999|2000|H04M001/02 1|1999|2000|H04M001/275 2|1991|1992|C12N015/62 2|1991|1992|C12N015/09 2|1991|1992|C07K019/00 2|1991|1992|C07K016/26 Thanking You [[alternative HTML version deleted]]

HOW TO FILTER DATA
Try the code below: df <- read_delim("C:/Users/lruan1/Desktop/1112.csv", "|", escape_double = FALSE, trim_ws = TRUE) df_new <- subset(df,df$IPC == 'H04M001/02'| df$IPC == 'C07K016/26' ) You can add more condition with "|" in the subset function.
