As you see in the data.. each section has table header followed by a row of
table column headers and then rows of data. I felt read.table may not be the
optimal function to extract both the texts (headers) and numerics
(rows&columns of data). As of now, I use "scan" to get the text boundaries
and use read.table to read the data within those boundaries. I wanted to
know if there is more efficient way of handling disparate sets of data

Thanks,
Santosh
