Hi,
Is it possible to do something similar to
boxplot(data.frame(m))
but have different scales for each of the boxplots?
The reason I ask is that I have a series of lake chemistry measurements
and I want to plot a diagram with boxplots for a number of variables.
The variables are measured in different units and some variables are
orders of magnitude bigger than others. Any help with this would be
appreciated.
Using R 1.3.0 on NT4
Cheers
Gav
