Dear group, I have been struggling to barplot two different measurements from one subject. These two measures differ in range. I want to plot row 1 axis on left side and row 2 values on right side.For a given column I want to plot GN and CN next to each other. my dput code is below : structure(c(112L, 0L, 579L, 1L, 131L, 1L, 2234L, 2L, 2892L, 1L, 528L, 0L, 582L, 2L), .Dim = c(2L, 7L), .Dimnames = list(c("GN", "CN"), c("DC5", "DC8", "DC14", "DC18", "DC19", "DC20", "DC23" ))) As you can see: DC5 DC8 DC14 DC18 DC19 DC20 DC23 GN 112 579 131 2234 2892 528 582 CN 0 1 1 2 1 0 2 GN values are range from 100 - 3000 while CN are always -2 or -1 or 0 or 1 or 2 Also I cannot log GN values and plot because a difference in 100 units also matters in my experiment. Any help would be greatly appreciated.
I would simply rescale one row and add a second axis. For example, if d holds your matrix:
scale <- max(d[1,])/max(d[2,]) adjusted <- d adjusted[2,] <- scale*adjusted[2,] barplot(adjusted, beside = TRUE) ticks <- pretty(d[2,]) axis(side = 4, at = ticks*scale, labels = ticks) Duncan Murdoch ______________________________________________ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
