[jira] Commented: (MATH-448) Frequency get number of unique values

["Sebb (JIRA)" <ji...@apache.org>]

    [ https://issues.apache.org/jira/browse/MATH-448?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12967244#action_12967244 ] 

Sebb commented on MATH-448:
---------------------------

Thanks for the patch, however it is not usable as it stands, as it is not in the correct format.

Patches need to be unified diffs, in plain text (not RTF as appears to be the case here).

> 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!
