 From ?scan :

If |comment.char| occurs (except inside a quoted character field), it 
signals that the rest of the line should be regarded as a comment and be 
discarded. Lines beginning with a comment character (possibly after 
white space with the default separator) are treated as blank lines.

So, set comment.char="#"

and you should be fine.

The combination of some data and an aching desire for 
an answer does not ensure that a reasonable answer 
can be extracted from a given body of data.
