Set names for a single axis of an array

• rray_set_axis_names() sets the names for a single axis of an array, leaving every other axis untouched. The titles of x are kept.

• rray_set_row_names() and rray_set_column_names() are shortcuts for rray_set_axis_names(x, 1, names) and rray_set_axis_names(x, 2, names).

Usage

rray_set_axis_names(x, axis, names)

rray_set_row_names(x, names)

rray_set_column_names(x, names)

Arguments

x

An array.

axis

The axis to set names for, given by position or by title.

names

A character vector of names for axis, the same length as the dimension of axis. Can also be NULL to remove names from axis.

Value

x with new names for axis.

Examples

x <- array(1:6, c(2, 3))

rray_set_axis_names(x, 1, c("r1", "r2"))
#>    [,1] [,2] [,3]
#> r1    1    3    5
#> r2    2    4    6
rray_set_axis_names(x, 2, c("c1", "c2", "c3"))
#>      c1 c2 c3
#> [1,]  1  3  5
#> [2,]  2  4  6

# By title
y <- rray_set_titles(x, c("row", "col"))
rray_set_axis_names(y, "col", c("c1", "c2", "c3"))
#>       col
#> row    c1 c2 c3
#>   [1,]  1  3  5
#>   [2,]  2  4  6

rray_set_row_names(x, c("r1", "r2"))
#>    [,1] [,2] [,3]
#> r1    1    3    5
#> r2    2    4    6
rray_set_column_names(x, c("c1", "c2", "c3"))
#>      c1 c2 c3
#> [1,]  1  3  5
#> [2,]  2  4  6
