		int *	p,
		int	np,
		void *	x,
		int	nnz,
		int *	dims,
		SEXP	dimnames,
		int	index1
	)

Create a Csparse matrix object from indices and/or pointers.

Parameters:

cls	name of actual class of object to create
i	optional integer vector of length nnz of row indices
j	optional integer vector of length nnz of column indices
p	optional integer vector of length np of row or column pointers
np	length of integer vector p. Must be zero if p == (int*)NULL
x	optional vector of values
nnz	length of vectors i, j and/or x, whichever is to be used
dims	optional integer vector of length 2 to be used as dimensions. If dims == (int*)NULL then the maximum row and column index are used as the dimensions.
dimnames	optional list of length 2 to be used as dimnames
index1	indicator of 1-based indices

Returns:: an SEXP of class cls inheriting from CsparseMatrix.
