Hi, I am looking for a way to analyze a dataset with a circular dependent variable and three independent factors. To be specific, the circular variable comprises of arrival times of pollinators to flowers. The independent variables are pollinator species, flower sex and locality. I have failed to find a way how to include all three factors. The "circular" package seems to enable testing of a single factor - or am I wrong? Does the "circular" or any other package enables to perform such analysis?
