identical_byname {matsbyname} | R Documentation |
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 ( |
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)
