n

Number of distinct rows (maximum); repeated rows are merged (argument addrepeats is TRUE)

vals

Values to use for coefficients

arity

Arity of the spray; the number of columns in the index matrix

powers

Set from which to sample the entries of the index matrix

Value

Returns a spray object

Note

If the index matrix contains repeated rows, the returned spray object will contain fewer than n entries
