calculating correlation coefficients on repeated measures
...ing two individual measures (e.g. P1 and P2, P2 and P3, etc.) and only if I restructure my table. Any suggestions: In SAS with 'proc corr' I would like results that look like: Individual ID, r, p WW_08I_01,-0.03,0.94 WW_08I_03,0.53,0.14 Trying to get started in R!
