r - How to plot a list of vectors with different lengths?

Question

I have a list with 9 different vectors inside. And I want plot them (dot-line) in one figure with different colors by their names. How to do that in R language?

Answer 1

Using a made up example:

# example data:
dat <- list(a=1:5,b=2:7,c=3:10)
# get plotting:
plot(unlist(dat),type="n",xlim=c(1,max(sapply(dat,length))))
mapply(lines,dat,col=seq_along(dat),lty=2)
legend("topleft",names(dat),lty=2,col=seq_along(dat))
