Get an OpenML data set.

Given a data set ID, the corresponding OMLDataSet will be downloaded (if not in cache) and returned.

Note that data splits and other task-related information are not included in an OMLDataSet. Tasks can be downloaded with getOMLTask.

getOMLDataSet(data.id = NULL, data.name = NULL, data.version = NULL,
  cache.only = FALSE, verbosity = NULL)

Arguments

data.id	[integer(1)] ID of the data set.
data.name	[character(1)] Data set name. This is an alternative to data.id. Default is NULL.
data.version	[integer(1)] Version number of the data set with name data.name. Default is NULL. Ignored if data.id is passed.
cache.only	[logical(1)] Only try to retrieve the object from cache. Will result in error if the object is not found. Default is FALSE.
verbosity	[integer(1)] Print verbose output on console? Possible values are: 0: normal output, 1: info output, 2: debug output. Default is set via setOMLConfig.

Value

[OMLDataSet].

Note

One of data.id or data.name must be passed.
