How did I make this plot?

To make this plot, I used R's plot(), points() and lines() commands. If you have been wanting to learn how to plot in R, watch it unfold in this video tutorial:



Also, here's the code I used:

	## ---------------------------- ##
	## Plotting Points *and* Lines ##
	## ---------------------------- ##
	## Define the Vectors I used in the video ##
	pow = c(0.95, 0.6, 0.3, 0.15, 0.1, 0.05, 0.1, 0.15, 0.3, 0.6, 0.95)
	pow2 = c(0.99, 0.75, 0.4, 0.2, 0.15, 0.05, 0.15, 0.2, 0.4, 0.75, 0.99)
	thet = c(7:17)
	plot(thet,pow) ## Plots points
	plot(thet,pow2) ## Plots points on *new* plot
	## But we want them on the same plot...
	## Try options in plot
	## Useful options in plot()
	plot(thet,pow, type="l", col="red") ## Lines
	plot(thet,pow, type="o", col="blue") ## Overplotted lines and points
	plot(thet,pow, type="s", col="orange") ## Stair steps
	## Less useful options
	plot(thet,pow, type="b") ## "Both" lines and points
	plot(thet,pow, type="c") ## "lines" part of "both"
	plot(thet,pow, type="h", xlim=c(0, 20),ylim=c(0,1)) ## Histogram-like
	plot(thet,pow, type="n",xlim=c(0, 20),ylim=c(0,1)) ## No plotting... ?
	## Note: xlim = c(low,high) sets low to be the lower limit for the x-axis and high to be the upper limit.
	## ylim = c(low,high) does the same for the y-axis. These can be useful for
	## Points and Lines to put on top of the active plot
	plot(thet,pow, type="n",xlim=c(0, 20),ylim=c(0,1)) ## No plotting... ?
	points(thet,pow2, col="blue")
	lines(thet,pow2, col="green")
	lines(thet,pow, col="red", type="o") ## plot() options work for lines() and points()
	title("My Power Plot") ## Sometimes it is nice to add a title
