Force a spam Object to Belong to a Class

These functions manage the relations that allow coercing a spam object to a given class.

Methods

signature(from = "spam", to = "matrix")

this is essentially equivalent to as.matrix(object).

signature(from = "spam", to = "list")

this is essentially equivalent to triplet(object).

signature(from = "spam", to = "vector")

this is essentially equivalent to object@entries (structurebased=TRUE) or c(object).

signature(from = "spam", to = "logical")

the entries are forced to logicals (nonzeros only in case of structurebased=TRUE).

signature(from = "spam", to = "integer")

the entries are forced to integers (nonzeros only in case of structurebased=TRUE).

Examples

ifelse( diag.spam(2)*c(0,1), TRUE, FALSE)
#> [1] FALSE FALSE FALSE  TRUE
