R: Put files with the same unit measurements into directories

unitize_dirs {filesstrings} | R Documentation

## Put files with the same unit measurements into directories

### Description

Say you have a number of files with "5min" in their names, number with "10min" in the names, a number with "15min" in their names and so on, and you'd like to put them into directories named "5min", "10min", "15min" and so on. This function does this, but not just for the unit "min", for any unit.

### Usage

    unitize_dirs(unit, pattern = NULL, dir = ".")

### Arguments

`unit` | The unit upon which to base the categorizing.
`pattern` | If set, only files with names matching this pattern will be treated.
`dir` | In which directory do you want to perform this action (defaults to current)?

### Details

This function takes the number to be the last number (as defined in `nth_number()`) before the first occurrence of the unit name. There is the option to only treat files matching a certain pattern.

### Value

Invisibly `TRUE` if the operation is successful, if not there will be an error.

### Examples

    ## Not run:
    dir.create("UnitDirs_test")
    setwd("UnitDirs_test")
    files <- c("1litres_1.txt", "1litres_3.txt", "3litres.txt", "5litres_1.txt")
    file.create(files)
    unitize_dirs("litres", "\\.txt")
    setwd("..")
    dir.remove("UnitDirs_test")
    ## End(Not run)
