R help - Apr 2010 - Error in leaps.setup

Hullo,
I am trying to use the leaps package, & keep getting the following error:
Error in leaps.setup(x, y, wt = wt, nbest = nbest, nvmax = NCOL(x) + int,  : 
  y and x different lengths

My data set is attached below.
I am rather new to R, & would appreciate any help that could be given. 

Thanks.

x might be a data frame rather than a matrix.

In any case, although you don't say, my psychic debugging powers tell me
that you are using the leaps() function from the package.  Use regsubsets()
instead. As the help page indicates, leaps() is just there for compatibility
with S-PLUS.

No, it isn't.  It may have been stripped off by the mailing list.
