Hi All,
I have googled and tried finding if someone has ever tried producing
(Grouped + Stacked) Barplot. I couldn't find one.
I think you need to define some dummy Factor1 categories with zero
heights and blank labels to separate your groups. Once that is done,
you can just use typical stacked bar graphs.
(Another barplot function to consider:

)
My data needs to be reshaped, but once it is done it would be
something like
this:
Factor1 Factor2 Factor3 Value
A X P 10
A X Q 20
A Y P 20
A Y Q 5
A Z P 20
A Z Q 10
B X P 20
B X Q 10
B Y P 30
B Y Q 50
B Z P 10
B Z Q 20
There are three categorical variables (Factor1, Factor2, and Factor3
having
2,3, and 2 levels resp.). I'm trying to plot "Factor1" on x axis --
each
level of this factor should have three (grouped) bars (one for each
level of
Factor2). Which will further be stacked by each level of Factor3.
Can anyone guide me please, thanks,
