Examples

m <- matrix(c(1:6), nrow = 2, dimnames = list(paste0("i", 1:2), paste0("c", 1:3))) %>%
  setrowtype("Industries") %>% setcoltype("Commodities")
getrownames_byname(m)
#> [1] "i1" "i2"
# This also works for lists
getrownames_byname(list(m,m))
#> [[1]]
#> [1] "i1" "i2"
#> 
#> [[2]]
#> [1] "i1" "i2"
#> 
DF <- data.frame(m = I(list()))
DF[[1,"m"]] <- m
DF[[2,"m"]] <- m
getrownames_byname(DF$m)
#> [[1]]
#> [1] "i1" "i2"
#> 
#> [[2]]
#> [1] "i1" "i2"
