[R] Shaded area

[John Kane]

As Peter says, the list is very cautious about what types of files it
allows. A handy way to supply some sample data is the dput() function.  In
the case of a large dataset something like dput(head(mydata, 100)) should
supply the data we need. Just do dput(mydata) where *mydata* is your data.
Copy the output and paste it here.
