Statistics[SelectInRange] - select data items in a given range

Statistics[RemoveInRange] - remove data items in a given range

Calling Sequence

SelectInRange(X, R, options)

RemoveInRange(X, R, options)

Parameters

X

-

data sample

R

-

data range

options

-

(optional) equation of the form include=value

Description

• 

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.

Options

  

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.

Notes

• 

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.
