Hello everyone, I want to do a seasonal pattern analysis of a disease incidence. I have the data on incidence number in each month for 3 years. I saw a good package called "season" in R. But it looks like it does the analysis for monthly, weekly or daily fashion. But I need to do the analysis for summer, winter, spring and autumn. Can anybody give me some help on choosing most suitable package to do this? Thanks much ARshad
