Hi Uwe, Here's one way to get your spider plot: ld1<-matrix(sample(1:5,310,TRUE),nrow=31) ld2<-apply(ld1,2,table) radial.plot(ld2,line.col=2:6,rp.type="p", radial.pos=seq(0,9*pi/5,by=pi/5), labels=paste("Q",1:10,sep=""),start=pi/2, clockwise=TRUE,main="Frequency of response by question") par(xpd=TRUE) legend(8,12,1:5,col=2:6,lty=1) par(xpd=FALSE) Quite a bit of overlap on the polygons, however.
