R Documentation

Merge two configurations. Always use as `config::merge()`.

Merge one configuration into another recursively.

merge(base_config, merge_config)

`base_config`	Configuration to merge values into
`merge_config`	Configuration to merge values from

Configuration which includes the values from merge_config merged into base_config.

We strongly recommend you use config::get() rather than attaching the package using library(config).

In fact, we strongly recommend you never use library(config).

The underlying reason is that the get() and merge() functions in {config} will mask these functions with the same names in base R.
