You know when you do a correlation plot in excel and get given an equation for the line in addition to the R2 value. I would like to do correlation plots within Perl, without producing graphical displays. I would then like to represent these correlations in a table. Does anyone have any experience of this and can anyone recommend modules for this? I will want to do about 10,000 correlations. Each correlation will have about 100 x-y coordinated points. These x-y coordinates will be pulled from a database.
