HSA calculates the synergy score matrix for a block of drug combination by using Highest Single Agent (HSA) reference model.

1	HSA(response)

response

A data frame. It must contain the columns: "conc1", "conc2", ..., for the concentration of the combined drugs and "response" for the observed %inhibition at certain combination.

This model is a reference model for evaluating the combination effect of two drugs. The basic assumption of this model is "The reference effect of drug combination is the maximal single drug effect".

A data frame containing the concentrations for drugs, reference effect and synergy score estimated by HSA model.
