LinkedMatrix-class {LinkedMatrix}

A Class Union of ColumnLinkedMatrix and RowLinkedMatrix

Description

This class is abstract and no objects can be created from it. It can be used to check whether an object is either of type ColumnLinkedMatrix or of type RowLinkedMatrix using is(x, "LinkedMatrix") and to assign methods for both ColumnLinkedMatrix and RowLinkedMatrix classes, e.g. show.

Methods

• length

• as.matrix

• show

• initialize

ColumnLinkedMatrix-class and RowLinkedMatrix-class for implementations of column-linked and row-linked matrices.

Examples

# Create an example RowLinkedMatrix from various matrix-like objects that
# correspond in dimensions
m <- RowLinkedMatrix(
    ff::ff(initdata = rnorm(50), dim = c(5, 10)),
    bigmemory::big.matrix(init = rnorm(50), nrow = 5, ncol = 10),
    matrix(data = rnorm(50), nrow = 5, ncol = 10)
)

# Test if m is an object of either type ColumnLinkedMatrix or RowLinkedMatrix
if (is(m, "LinkedMatrix")) {
    message("m is a LinkedMatrix")
}
