Thank you, David.
Now I know how to use dput.
Two more questions conjured up when running the code:
1. If there are about 500 species of butterflies,
please kindly advise if it is possible to input the butterfly names
(for .Label) using code,
instead of keying in them one by one.
2. Aggregrate command
Last time we produced the mean of range sizes.
Please kindly advise if it is possible to produce barplot showing the
value range, instead of mean.
Thank you
Elaine
