## Write Chronology File

### Description

This function writes a chronology to a file in one of the available formats.

### Usage

    write.rwl(rwl.df, fname, format = c("tucson", "compact", "tridas"), ...)

### Arguments

`rwl.df` | a `data.frame` containing tree-ring ring widths with the series in columns and the years as rows. The series IDs are the column names and the years are the row names. This type of `data.frame` is produced by `read.rwl`.
`fname` | a `character` vector giving the file name of the rwl file.
`format` | a `character` vector giving the format. This must be `"tucson"`, `"compact"`, or `"tridas"`. Tucson format is the default.
`...` | arguments specific to the function implementing the operation for the chosen format.

### Details

This is a simple wrapper to the functions actually implementing the write operation.

### Value
