read_arff {mlr3oml}

Read ARFF files

Description

Parses a file located at path and returns a data.table().

Limitations:

• Only works for dense files, no support for sparse data. Use RWeka instead.

• Dates (even if there is no time component) are read in as POSIXct.

• The date-format from the ARFF specification is currently ignored. Instead, we rely on the auto-detection of data.table's fread()..

Usage

read_arff(path)

Arguments

path

(character(1))
Path or URI of the ARFF file, passed to file().

Value

(data.table()).
