x<-circular(dayofmax[,2]*2*pi/365) res25 <- density(x, bw=25, control.circular=list(units="degrees")) circularp(res25$x) plot(res25, col=4, points.plot=TRUE, xlim=c(-1.5,1.5)) res50 <- density(x, bw=50, adjust=2) lines(res50, col=2) lines(res50, col=3, shrink=0.9) this is my code, basically, it plots all my data on a circular. and the lines are telling where points are more dense than other places. so my problems is that im trying to change all the points in the circular plot. instead of have it being 0, 90, 180, 270... i would like to input my own stuff in there, such as Jan, Feb, March.... please help!! Thank you very much. [[alternative HTML version deleted]]
