Downloads multiple Parameter Configurations from the mlrHyperopt servers

Retrieve the Paramater Configurations for the given ids from the mlrHyperopt servers.

downloadParConfigs(
  ids = NULL,
  learner.class = NULL,
  learner.name = NULL,
  custom.query = NULL
)

Arguments

ids	[character] One ore more unique identifiers of the Parameter Set
learner.class	[character(1)] The learner.class you want to download the Parameter Configrations for.
learner.name	[character(1)] The learner.name you want to download the Parameter Configrations for.
custom.query	[list(2)] List of the form list(key = "key", value = "value") for custom queries.

Value

[List of ParConfigs]
