Hi BJ,
Suppose that your data set is called 'Data1', please copy and paste
the output created by typing:
dput(Data1[1:15, ])
and post that to the list ***in plain text*** (or upload a text file
on some file hosting service). The email you sent is nearly
impossible to parse because this is a plain text list (as noted in the
posting guide) and your html formatting is utterly lost.
