The SelectInRange function selects all items from X which belong to the specified range R and returns them in a new data sample with the same options as X.

The first parameter X is a data sample - given as e.g. a Vector.

The second parameter R is the range. By default the range R is considered closed from the left and open from the right. This can be changed using the include option.

The RemoveInRange function does the opposite of SelectInRange. It removes all data items from X which belong to the range R.

The options argument can contain the following option:

include=left, right or [left, right] -- Specify whether the endpoints should be included in the interval. By default, the interval defined by R is considered closed on the left and open on the right.

Each element of X can be any Maple expression, but this expression must be able to be evaluated to a floating-point number. Failure to do so will generate an error.

The SelectInRange and RemoveInRange commands leave the original data set X unchanged.
