The plotmeans() function uses the order of the factor levels. To change the
order in the plot, change the order of the factor levels.
For example:
> data(state)
> plotmeans(state.area ~ state.region)
Plots the groups in the order
levels(state.region)
> levels(state.region)
[1] "Northeast" "South" "North Central" "West"
You can change the order of the levels using the gdata:::reorder.factor
function:
> state.region <- reorder.factor(state.region, c("Northeast", "North Central",
> "South" "West")),
Now, doing
> plotmeans(state.area ~ state.region)
will show the plot with the new order.
