Important: The stats package has been deprecated. Use the superseding package Statistics instead.

The statvalue function of the subpackage stats[transform, ...] replaces each data point of data by its value. In other words, it resets the weight of each data point to 1.

The order of the data items is not changed.

Note that repeated items will still be repeated, though each instance will have a weight of 1. If it is required that only a single instance of the items remain, use transform[tally] prior to using transform[statvalue]. Of course, the call to tally will, in general, change the order of the data.

The name of this function is chosen to avoid the clash with the value() function.
