Range difference of plot two arrays in one plot
Hello David, When I used the same ylim for both plots, I got what I need: x = c(0,0,0,10,20,30) y = c(40,50,60,70,80,90) plot(x, type='o', ylim=c(min(x,y),max(x,y))) par(new=T) plot(y, type='l', ylim=c(min(x,y),max(x,y))) Thanks, Rebecca -----Original Message----- From: David Winsemius [mailto:dwinsemius at comcast.net] Sent: Friday, February 01, 2013 11:39 AM To: Yuan, Rebecca Subject: Re: [R] Range difference of plot two arrays in one plot

Hello all, When I tried to plot the following two arrays in one figure with the following: x = c(0,0,0,10,20,30) y = c(40,50,60,70,80,90) plot(x, type='o', ylim=c(min(x),max(x))) par(new=T) plot(y, type='l', ylim=c(min(y),max(y))) Found that the first points and last points from those two arrays are overlapping together, but the value 30 is not equal to 90. How could I draw those two arrays in one plot with their real values shown in the plot? i.e., x is in the lower part of the plot and y is in the upper part of the plot.
Use the same ylim for each plot?
