R: Set aliases for chunk options

set_alias {knitr} | R Documentation

## Set aliases for chunk options

### Description

We do not have to use the chunk option names given in knitr; we can set aliases for them. The aliases are a named character vector; the names are aliases and the elements in this vector are the real option names.

### Usage

    set_alias(...)

### Arguments

`...` | Named arguments. Argument names are aliases, and argument values are real option names.

### Value

`NULL`. `opts_knit$get('aliases')` is modified as the side effect.

### Examples

    set_alias(w = "fig.width", h = "fig.height")
    # then we can use options w and h in chunk headers instead of fig.width and
    # fig.height
