Subset species based on relative frequency.

1	sub.sp.matrix(spmatrix, freq = 0.5, common = NULL)

`spmatrix`	a standard community matrix with rows representing sites and columns representing species.
`freq`	The relative frequency, species with higher relative frequency will be kept in the output.
`common`	The number of most common species to keep.

sub.sp.matrix will select the species whose relative frequency above 0.5 (default), or select certain number of species based on relative frequency.

A subset matrix of species with high relative frequency.
