Correlation values from vocal interaction matrices

Calling interactions in group-housed zebra finches: correlation values from vocal interaction matrices for call-type and bird combinations, calculated from PSTHs. Matrices were transposed to columns (focal bird) and rows (non-focal bird), and supplemented with information on: Trial; day; identity, sex and call type of focal and non-focal bird; whether interacting birds were pair members (Pairmembers(y/no)); whether vocal interactions were positive, non-significant or negative (Interaction(pos/0/neg); how call types were combined (combination.type); whether focal bird was in a pair that produced a clutch of eggs (focal.eggslaid); reproductive stage of the focal bird (nest.stage = summary, breeding.stage = more detailed)
