[R] Identification of Outliners and Extraction of Samples

2010-08-09 Thread Alexander Eggel
Hello everybody, I need to know which samples (S1-S6) contain a value that is bigger than the median + five standard deviations of the column he is in. This is just an example. Command should be applied to a data frame wich is a lot bigger (over 100 columns). Any solutions? Thank you very much
