I would like to use the "row number" information returned from performing a subset command on a dataframe.
For example, I would like to automatically delete some rows from a dataframe if they match a criteria. Here is my example below.
subset(airquality, airquality$Month == 6)
Now how do I delete the row numbers returned automatically?
I know I can type
However, I would like to check the row information and then use it to delete the stuff out of the dataframe.
Thank again for any feedback and insights.
