variableNames

Description

Return the variable names of a MultiBlock object.

Usage

variableNames(x, ...)

## S4 method for signature 'MultiBlock'
variableNames(x, block)

Arguments

x	A MultiBlock object.
...	Not used. Present for S4 generic dispatch compatibility.
block	Optional. A vector of block names or indices to retrieve. When omitted, variable names for all blocks are returned as a named list. When a single block is specified, a plain vector is returned.

Value

A named list of variable-name vectors (all blocks), or a single vector when exactly one block is requested.

Examples

b1 <- matrix(rnorm(500), 10, 50)
b2 <- matrix(rnorm(800), 10, 80)
mb <- MultiBlock(Data = list(b1 = b1, b2 = b2))
variableNames(mb) # named list: b1 = 1:50, b2 = 1:80
variableNames(mb, "b1") # 1:50
variableNames(mb, 1:2) # same as variableNames(mb)
