Dear R users,
I need to draw a barplot with 2 Y axis. I have 3 days each of wich having 2 groups (and error bar
for each of them). The height of the 3rd day is too tall compared to others. That's why I have to
use a second Y axis for that. I am using "barplot2" function of "gplots"
library (to be able to add error bars as well). Data and codes currently I am using is below.
...
Any help regarding adding second Y axis is deeply apprecited.
Hi Seyit,
It is fairly easy to get the bars like this:
library(plotrix)
barpos<-barp(means,ylim=range(means+SEM)+c(0,4),col=2:3)
dispersion(barpos$x,barpos$y,CIU,CIL,interval=FALSE)
or even more simply:
dispersion(barpos$x,barpos$y,SEM)
I am not sure that you need an extra y axis here.
Jim
