identical_byname: Compare two matrices "by name" for exact equality

In matsbyname: An Implementation of Matrix Mathematics that Respects Row and Column Names

Compare two matrices "by name" for exact equality

Description

If operands are matrices, they are completed and sorted relative to one another prior to comparison.

Usage

identical_byname(..., .summarise = FALSE)

Arguments

...	Operands to be compared.
.summarise	Tells whether the operation should be accomplished across lists (FALSE) or down lists (TRUE).

Details

Comparisons are made by identical(a, b) so that variations among numbers within the computational precision will return FALSE.

If fuzzy comparison is needed, use equal_byname, which compares using isTRUE(all.equal(a, b)).

Value

TRUE iff all information is identical, including row and column types and row and column names and entries in the matrices.

Examples

a <- matrix(1:4, nrow = 2)
b <- matrix(1:4, nrow = 2)
identical_byname(a, b)
identical_byname(a, b + 1e-100)
a <- a %>% setrowtype("Industries") %>% setcoltype("Commodities")
identical_byname(a, b) # FALSE because a has row and column types, but b does not.
b <- b %>% setrowtype("Industries") %>% setcoltype("Commodities")
identical_byname(a, b)
dimnames(a) <- list(c("i1", "i2"), c("c1", "c2"))
dimnames(b) <- list(c("c1", "c2"), c("i1", "i2"))
identical_byname(a, b) # FALSE, because row and column names are not equal
dimnames(b) <- dimnames(a)
identical_byname(a, b)
