test individual values in rows
If your data.frame is completely numeric, this is easy. If your data.frame is called df, then do df[apply(df, 1, function(x) !all(x < 100)),] Look at ?apply Best, Erik Iverson

Hi list. I have a numerical dataset 22,000 rows deep and 43 columns wide. I would like to remove those rows which contain only values less than 100 (ie if any value in the row is greater than 100 the row stays in the dataset). I am unsure how to test each individual value across the rows and then identify the rows which meet my criteria. Can anyone help? Thank you. Iain [[alternative HTML version deleted]]
