[jira] Updated: (MATH-448) Frequency get number of unique values
[ https://issues.apache.org/jira/browse/MATH-448?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
Patrick Meyer updated MATH-448:
-------------------------------
Attachment: Frequency.diff
> Frequency get number of unique values
> -------------------------------------
>
> Key: MATH-448
> URL: https://issues.apache.org/jira/browse/MATH-448
> Project: Commons Math
> Issue Type: New Feature
> Reporter: Patrick Meyer
> Priority: Minor
> Attachments: Frequency.diff
>
> Original Estimate: 0.25h
> Remaining Estimate: 0.25h
>
> It is often useful to know the number of unique elements in a frequency table. Could you add a simple method that returns the size of freqTable. It seems like it would be as simple as:
> {code}
> public int getUniqueCount(){
> return freqTable.size();
> }
> {code}
> Given that freqTable is private, there is no way to extend the class and add this method. Thanks!
