Dear List
I am trying to draw a heatmap using ggplot2. In this heatmap I have faceted my
data by 'infection' of which I have four. These four infections break down into

reflect this.
Toy example below:

Hi:
(1) Here is one way to reorganize the levels of a factor:
plotData[['infection']] - factor(plotData[['infection']],
levels = c('InfA', 'InfC', 'InfB', 'InfD'))
Do this ahead of the call to ggplot(), preferably after plotData is defined.
relevel() resets the
