preselect.R Don't assume multiple identical plates

[bethac07]

preselect.R assumes that replicates can be found by looking for 2 plates that have an identical "Metadata_Plate_Map_Name" and then saying the replicates are just a matter of matching wells across these identical plates.

In some experiments, however, each plate may be unique, and replicates may be found in either a different location on the same (or even another) plate. Allowing the user an optional flag to pass something else would be helpful.

This can be done but note that two plates with the same Metadata_Plate_Map_Name should be identical. If they are not, then they have different plate maps.

Nonetheless, it makes sense to be able to specify other grouping variables to define replicates

Completely on board with this. 😄

TY!
