## Read configuration values

### Description

Read from the currently active configuration, retreiving either a single named value or all values as a list.

### Usage

    get(value = NULL, config = Sys.getenv("R_CONFIG_ACTIVE", "default"),
      file = Sys.getenv("R_CONFIG_FILE", "config.yml"), use_parent = TRUE)

### Arguments

`value` | Name of value (`NULL` to read all values)
`config` | Name of configuration to read from. Defaults to the value of the `R_CONFIG_NAME` environment variable ("default" if the variable does not exist).
