Is there a special need to do it recursively?

Would the following not do the trick, too?

m <- matrix(c(1,6,3,2,5,4,3,6,3,4,5,4), byrow=TRUE, ncol=3)
matplot(m, type="o", xaxt="n",ylim=c(min(m[,1:length(colnames(m))])-1,
max(m[,1:length(colnames(m))])+1),
lty=1, col="black")

Or simply:
matplot(m, type="o", xaxt="n", lty=1, col="black")

Hope this helps,
Roland
