Re: [R] multiple line plots

Assuming, as in your example, that you want to plot your series against 1, 2, 3, ... first form a ts series, my.series, and then plot it using the col= argument:

	my.series <- do.call("cbind", lapply(tpos, ts))
	m <- ncol(my.series)
	ts.plot(my.series, col = 1:m)

Another possibility is to use col = rainbow(m) in the last line.
