I have csv files imported in r each with 2 columns and many many rows. I have sorted the data in them but want to extract some values.

"p-value" is a rather unlikely R name for a column since it is illegal in R. Using a "table" is also unlikely, so let's assume that once you have read it into a dataframe, that it's named p_value. AnovaSort[AnovaSort$p_value < 0.05] David Winsemius, MD Heritage Laboratories West Hartford, CT
