First, load the packages and data:
library("ggplot2")library("cdata") iris <- data.frame(iris)
Now define the data-shaping transform, or control table. The control table is basically a picture that sketches out the final data shape that I want. I want to specify the
ycolumns of the plot (call these the value columns of the data frame) and the column that I am faceting by (call this the key column of the data frame). And I also need to specify how the key and value columns relate to the existing columns of the original data frame.
Read on to see how you can use
cdata to tie together different faceted plots.
