SelectNonNumeric(X, options)
RemoveNonNumeric(X, options)
X
-
data sample
options
(optional) equation of the form exclude=value
The SelectNonNumeric function selects non-numeric items from X and returns them in a new data sample. Note, that an expression X is considered non-numeric if evalfX does not return a floating-point number. Numeric items are discarded in the newly created data sample.
The first parameter X is a data sample - given as e.g. a Vector.
The RemoveNonNumeric function does the opposite of SelectNonNumeric. It removes the non-numeric values from X.
The options argument can contain one or more of the options shown below.
exclude=infinity, undefined, or [infinity, undefined] -- By default, undefined and infinity are considered non-numeric. This can be changed by adding infinity or undefined or both to the exclude list. Thus, exclude=undefined means that infinity should still be considered numeric but undefined should not.
