Gets row names in a way that is amenable to use in chaining operations in a functional programming way

getrownames_byname(a)

Arguments

a

The matrix or data frame on which row names are to be retrieved

Value

row names of a

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" #>
