dataframe - How to delete rows from a data.frame, based on an external list, using R?

Question

This might be an easy question but i still need some help for using R.

I have a data.frame (main_data), lets say..

NAMES   AGE     LOC
Jyo     23      Hyd
Abid    27      Kar
Ras     24      Pun
Poo     25      Goa
Sus     28      Kar

I wish to remove a few rows based on a list of names. So lets say I have another list of table as follows:

NAMES_list
Jyo
Ras
Poo

So based on this list, if any of the names match to my above "main_data" table, then I would like to remove the whole row contianing them, so the result should be as follows

NAMES   AGE     LOC
Abid    27      Kar
Sus     28      Kar

Can anyone help me how to achive this using R? Thanks in advance.. :)

Use %in%:

main_data2 <- main_data[ ! main_data$NAMES %in% NAMES_list, ]
