v <- matrix(c(1,
2,
3,
4),
nrow = 4, ncol = 1, dimnames = list(c("p1 -> i1",
"p2 -> i1",
"p1 -> i2",
"p2 -> i2"))) %>%
setrowtype("Products -> Industries")
# Default separator is " -> ".
matricize_byname(v, notation = RCLabels::arrow_notation)
#> i1 i2
#> p1 1 3
#> p2 2 4
#> attr(,"rowtype")
#> [1] "Products"
#> attr(,"coltype")
