Represents a pairwise similarity or distance matrix.
as.PairwiseMatrix(x, ...)# S4 method for matrix
as.PairwiseMatrix(x, ...)
# S4 method for PairwiseMatrix
as.matrix(x, ...)
an R object.
additional arguments to be passed to methods.
.Dataentries of the matrix in column-major order. Entries in the upper triangle and/or on the diagonal may be omitted.
Diminteger vector of length 2. The dimensions of the matrix.
Diaglogical indicating whether the diagonal entries are stored in
.Data.
If the elements being compared are from the same set, the matrix may be symmetric if the comparator is symmetric. In this case, entries in the upper triangle and/or along the diagonal may not be stored in memory, since they are redundant.
