You did well to include example data and code in your query. You would
likely have received a more rapid reply if you had made your example
simpler, leaving out details that are not relevant to your question. Also,
it is very helpful to the readers of this list if you share your data
using the output of dput(), so that it is easy to read in, and each column
is of the appropriate class.
There is no need for you to specify tick marks using the pretty()
function, as this is what most R graphing functions use by default. In
order to extend the limits on the yaxis, use the ylim= argument in the
graphing functions. A much simplified version of your graph is created by
the code below.
