broadcast {dibble}

Broadcast to a new dimension

Description

Broadcasts the dimension of the object to a new dimension.

Usage

broadcast(x, dim_names = NULL, ...)

## Default S3 method:
broadcast(x, dim_names = NULL, ...)

## S3 method for class 'ddf_col'
broadcast(x, dim_names, ...)

## S3 method for class 'tbl_ddf'
broadcast(x, dim_names, ...)

Arguments

x

A dibble, vector, or array.

dim_names

A character vector or list of dimension names.

...

Unused, for extensibility.

Details

Operations between dibbles are automatically broadcasted, but for safety reasons, warnings are issued. broadcast() can suppress the warnings if dim_names matches the dimension of x.

Value

A dibble.

Examples

x <- broadcast(1:2,
               list(axis1 = letters[1:2]))
y <- broadcast(1:3,
               list(axis2 = letters[1:3]))
broadcast(x * y, c("axis1", "axis2"))
