Odp: 2 plots with different scales in the same graphical window
Hi r-help-bounces at r-project.org napsal dne 09.12.2010 16:25:06:
Dear useRs, I have two sets of data that I would like to plot in the same window,
but their
ranges are really different, e.g. a <- c(0.2, 0.5, 0.8, 0.3, 0.4, 0.5, 0.2, 0.2, 0.3) b <- c(100, 2000, 800, 200, 100, 50, 4, 2, 0) If I do plot(a, ty='l'); points(b, ty='l') I won't be able to see sequence b. However, if I do plot(b, ty='l'); points(a, ty='l') I won't be able to see the patterns in sequence a. So is there a way of plotting sequence a and b without applying log or anything, but sequence a would be correspondent to the left y-axis and
sequence
b correspondent to the right y-axis?
See twoord.plot from plotrix. Or search archuves for a function plot.yy (I posted it few years ago). Regards Petr
Thanks in advance, Best, Rafael. [[alternative HTML version deleted]]
