[R] help with stacked ggplot

[Jeff Newmiller]

If you look below at the detritus of your posting you will see why we are 
always reminding people to adjust their email programs to send PLAIN 
TEXT... since this is a plain text mailing list and HTML formatted email 
does not come through reliably. This and other ground rules are laid out 
in the Posting Guide mentioned in the footer of every email on the mailing 
list.

I also recommend looking into the reprex package... it can conveniently 
check any code example to confirm that it is self-contained so it should 
run on our computers and we can see your progress. The dput function is 
also useful for giving us a snippet of data in our R environments (not 
much to look at, but makes R quite happy). I am going to pass on trying to 
decipher the mess below.

However, I think the key to answering your query is learning how to create 
factor columns in your data set (hint: use the factor function, not the 
as.factor function). The order of the labels in the factor is preserved in 
the plot (assuming the structure of the plot is not too complicated), so 
you can use scale_* functions such as scale_fill_manual to control the 
corresponding graphical appearance.
