## Not Yet Implemented Functions and Unused Arguments

### Description

In order to pinpoint missing functionality, the R core team uses these functions for missing R functions and not yet used arguments of existing R functions (which are typically there for compatibility purposes).

You are very welcome to contribute your code ...

### Usage

    .NotYetImplemented()
    .NotYetUsed(arg, error = TRUE)

### Arguments

`arg` | an argument of a function that is not yet used.
`error` | a logical. If `TRUE`, an error is signalled; if `FALSE`; only a warning is given.

### See Also

the contrary, `Deprecated` and `Defunct` for outdated code.

### Examples

    require(graphics)
    require(stats)
    plot.mlm         # to see how the "NotYetImplemented"
                     # reference is made automagically
    try(plot.mlm())

    barplot(1:5, inside = TRUE) # 'inside' is not yet used
