Hi, I have a few methodological and implementation questions for ya'll. Thank you in advance for your help. I have a dataset that reflects people's preference choices. I want to see if there's any kind of clustering effect among certain preference choices (e.g. do people who pick choice A also pick choice D).

Dear all, I am still fairly new to R and try to analyze large tables of data generated from genomic experiment. Currently, I am trying to plot pair of experiments coming from different file, trying to look at the behavior of individual feature in pair of experiment.

Stephen, This REALLY needs to be fixed in the code; tc should reject as a syntax error any "add filter" command that does not include a "prio" parameter. It also needs to be documented. === From LARTC mailing list === > Dear list, > After much code crunching and beating my head against the wall > (literally), I discovered the faulty code.
