[R] make three plot to one plot

[Gabor Grothendieck]

# we can create a zoo object
library(zoo)
z <- merge(five = zoo(test.five.y, test.five.x),
	six = zoo(test.six.y, test.six.x),
	seven = zoo(test.seven.y, test.seven.x))

# and then plot it all in one go using na.approx to fill in generated NAs
plot(na.approx(z), plot.type = "single", xlab = "x", ylab = "y", ,col = 1:3)

# Finally add the legend
legend("topright", xjust = 1, lty = 1,
      legend = c("five", "six", "seven"),
      col = 1:3)
