I am trying to import a series of text files generated by stimulus
presentation software.  The problem that I am having is that the number of
rows I need to skip is not fixed (depending on subject's pretest behavior)
nor is the first row of the data I want always the same (the stimuli were
presented in random order).  So I need to bring in the .txt file (using
readLines?), look for the row containing the text "Begin Main" (see exact
row below) and start reading data to a table from that point.

 [13] "Main Group\t1000\tBegin Main\tBegin Main\tBegin Main\t\t
\tPressed\t(any response)\tC\t25860\t\t\t\t\t"

I would also like it to ignore the row:
[173] "Main Group\t1000\tBreak\tBreak\
tpause3\t\t \tPressed\t(any response)\tC\t47610\t\t\t\t\t"

which will always be the same number of rows after the "Begin Main" row.

Thanks,
Kevin Burnham
