Inspect or change DATA.
Arguments
- x
A px object
- value
Optional. A data frame. If missing, the current DATA is returned. If NULL, all data rows are removed.
- validate
Optional. If TRUE a number of validation checks are performed on the px object, and an error is thrown if the object is not valid. If FALSE, the checks are skipped, which can be usefull for large px objects where the check can be time consuming. Use
px_validate()
to manually preform the check.
Details
If adding a new data frame, metadata is generated for the new columns and removed for columns that are no longer present.
