MplusAutomation (version 0.6-1)

cd: Change directory

Description

The function takes a path and changes the current working directory to the path. If the directory specified in the path does not currently exist, it will be created.

Usage

cd(base, pre, num)

Arguments

base

a character string with the base path to the directory. This is required.

pre

an optional character string with the prefix to add to the base path. Non character strings will be coerced to character class.

num

an optional character string, prefixed by pre. Non character strings will be coerced to character class.

Value

• NULL, changes the current working directory

Details

The function has been designed to be platform independent, although it has had limited testing. Path creation is done using file.path, the existence of the directory is checked using file.exists and the directory created with dir.create. Only the first argument, is required. The other optional arguments are handy when one wants to create many similar directories with a common base.

Examples

# an example just using the base
cd("~/testdir")

# an example using the optional arguments
base <- "~/testdir"
pre <- "test_"

cd(base, pre, 1)
cd(base, pre, 2)
