setcolnames_byname: Sets column names

In MatthewHeun/matsbyname: An Implementation of Matrix Mathematics that Respects Row and Column Names

Sets column names

Description

Sets column names in a way that is amenable to use in piping operations in a functional programming way. if a is NULL, NULL is returned. If a is a constant, it is converted to a matrix and colnames are applied. If a is a matrix, colnames should be a vector of new column names that is as long as the number of columns in a. If a is a list of matrices, colnames can also be a list, and it should be as long as a. Or colnames can be a vector of column names which will be applied to every matrix in the list of a. Each item in the list should be a vector containing column names for the corresponding matrix in a.

Usage

setcolnames_byname(a, colnames)

Arguments

a	A matrix or a list of matrices in which column names are to be set
colnames	A vector of new column names or a list of vectors of new column names

Value

a copy of a with new column names

Examples

m <- matrix(c(1:6), nrow = 2, dimnames = list(paste0("i", 1:2), paste0("c", 1:3))) %>%
  setrowtype("Industries") %>% setcoltype("Commodities")
setcolnames_byname(m, c("a", "b", "c"))
