Change specification notation
switch-notation.Rd
IEA data can be "specified" by adding additional information. Three notations are useful: arrow, bracket, and from. Arrow notation is from -> to, and bracket notation is destination [source]. These functions change matrix row/column names among the notations.
arrow_to_from_byname()
switches from arrow notation to from notation.from_to_arrow_byname()
switches from from notation to arrow notation.arrow_to_bracket_byname()
switches from arrow notation to bracket notation.bracket_to_arrow_byname()
switches from bracket notation to arrow notation.
Functions with the _byname
suffix behave like functions in the matsbyname
package.
Specifically, they can work with a single matrix or a list of matrices supplied to the m
argument.
Examples
m <- matrix(c(1, 2,
3, 4), nrow = 2, ncol = 2, byrow = TRUE,
dimnames = list(c("a -> b", "c -> d"), c("f [e]", "h [g]")))
m
#> f [e] h [g]
#> a -> b 1 2
#> c -> d 3 4
arrow_to_from_byname(m)
#> f [e] h [g]
#> b [from a] 1 2
#> d [from c] 3 4
arrow_to_from_byname(m, margin = 2) # No changes expected.
#> f [e] h [g]
#> a -> b 1 2
#> c -> d 3 4
from_to_arrow_byname(m)
#> f [e] h [g]
#> a -> b 1 2
#> c -> d 3 4
arrow_to_bracket_byname(m)
#> f [e] h [g]
#> b [a] 1 2
#> d [c] 3 4
bracket_to_arrow_byname(m)
#> e -> f g -> h
#> a -> b 1 2
#> c -> d 3 4
