| print {spam} | R Documentation |
Printing (non-zero elements) of sparse matrices and summarizing the sparseness structure thereof.
print(x, ...) summary(object, ...)
x |
matrix of class spam or spam.chol.method. |
object |
matrix of class spam or spam.chol.method. |
... |
any other arguments passed
to print.default. |
.Spam$printsize determines if the sparse matrix is
coerced into a matrix and the printed as an array or if
only the non-zero elements of the matrix are given.
NULL, because the information is printed with cat there
is no real need to pass any object back. We also do not see the need
of defining a summary.spam class with a proper print
method.
