Hi All,

I need to parse data from a file, example shown below.  The first two lines
can be skipped, the third line contains the column names.  The next 13 lines
can be skipped.  The next line "1991" is a year value, with the following 13
values data for that year.  The file then repeats this format with (year, 13
lines of data for that year).  I would ideally like to end up with an
array/list/vector of the block of 13 values, indexed by year, each block
using the column names given on the third line.

If anyone has any good ideas on how to do this in R, pls. let me know.

Thanks,
Sean
