## Default S3 method:
listMeasures(obj, properties = character(0L), create = FALSE)

## S3 method for class 'character'
listMeasures(obj, properties = character(0L), create = FALSE)

## S3 method for class 'Task'
listMeasures(obj, properties = character(0L), create = FALSE)

Arguments

`obj`	(`character(1)` \| Task) Either `character(1)` task or the type of the task, in the latter case one of: “classif” “regr” “surv” “costsens” “cluster” “multilabel”. Default is `NA` matching all types.
`properties`	(character) Set of required properties to filter for. See Measure for some standardized properties. Default is `character(0)`.
