positive number. The base with respect to which logarithms
are computed. Defaults to e=exp(1).
Details
It is important to note that the zero entries do not enter the
evaluation when structurebased=FALSE. The operations are performed on the stored non-zero
elements. This may lead to differences if compared with the same
operation on a full matrix.
Value
If structurebased=TRUE, all functions operate on the vector x@entries and return the
result thereof.
Conversely, if structurebased=FALSE, the result is identical to
one with as.matrix(x) input and an as.spam purger.
