The config
package makes it easy to manage environment specific configuration values. For example, you might want to use distinct values for development, testing, and production environments.
You can install the config
package from CRAN by using:
install.packages("config")
To use config
, create a file config.yml
with default as well as other arbitrary configurations. For example:
```{yaml output.var="config_yaml"} default: trials: 5 dataset: "data-sampled.csv"
production: trials: 30 dataset: "data.csv"
To read configuration values you call the `config::get` function, which returns a list containing all of the values for the currently active configuration: ```r config <- config::get() config$trials config$dataset
You can also read a single value from the configuration as follows:
config::get("trials") config::get("dataset")
The config::get()
function takes an optional config
argument which determines which configuration to read values from (the "default" configuration is used if none is specified).
