R: Convert a Formula Transformed by 'denumerate'

renumerate {MASS} | R Documentation

## Convert a Formula Transformed by 'denumerate'

### Description

`denumerate` converts a formula written using the conventions of `loglm` into one that `terms` is able to process. `renumerate` converts it back again to a form like the original.

### Usage

    renumerate(x)

### Arguments

`x` | A formula, normally as modified by `denumerate`.

### Details

This is an inverse function to `denumerate`. It is only needed since `terms` returns an expanded form of the original formula where the non-marginal terms are exposed. This expanded form is mapped back into a form corresponding to the one that the user originally supplied.

### Value

A formula where all variables with names of the form `.vn`, where `n` is an integer, converted to numbers, `n`, as allowed by the formula conventions of `loglm`.

### See Also

`denumerate`

### Examples

    denumerate(~(1+2+3)^3 + a/b)
    ## ~ (.v1 + .v2 + .v3)^3 + a/b
    renumerate(.Last.value)
    ## ~ (1 + 2 + 3)^3 + a/b
