popBackupFile {R.utils} | R Documentation

## Drops a backup suffix from the backup pathname

### Description

Drops a backup suffix from the backup pathname and, by default, restores an existing backup file accordingly by renaming it.

### Usage

    ## Default S3 method:
    popBackupFile(filename, path=NULL, suffix=".bak", isFile=TRUE,
      onMissing=c("ignore", "error"), drop=TRUE, ..., verbose=FALSE)

### Arguments

`filename` | The filename of the backup file.
`path` | The path of the file.
`suffix` | The suffix of the filename to be dropped.
`isFile` | If `TRUE`, the backup file must exist and will be renamed. If `FALSE`, it is only the pathname string that will be modified. For details, see below.
`onMissing` | A `character` string specifying what to do if the backup file does not exist.
`drop` | If `TRUE`, the backup file will be dropped in case the original file already exists or was successfully restored.
`...` | Not used.
