st: RE: reshaping a data file: cell frequency = number of rows in the newdata set

["G. ter Riet" <G.terRiet@amc.uva.nl>]

Hi Scott,
I apologize. To answer your question,
now the data are structured as (data editor view)
a b c d
1 2 3 4
where a thru' d are the variable names denoting the cell frequencies; 
a=true positive test results; b=false positives; c=false negatives; 
d=true negatives.
