[R] FW: Combined grouped and stacked bargraph

[John Kane]

Hi Nicola,

You have provided the code and data as requested the data is in a very unfriendly format.

If you would  supply the data in an easily useable format so that the readers here can work with it it would help.

Since it looks like you have a small data set the easiest thing is to use dput()  [see ?dput for information] and then just paste the output into your email.  I expect you would get faster and better answers.
