Maximal size of the attribute entries

Dear RapidMiners,

Happy new year to everyone!

The new year already brings new questions! Here is one from me:

Is it possible to get the maximal length of the strings contained in an an attribute? For example, if in an attribute I am storing titles of web pages, is there an elegant way to retrieve the length of the longest title?

Many thanks in advance!

Cheers,

Snezana

Hi Snezana,

One way for doing this might be using 'Generate attributes' operator and length() function on a nominal attribute containing web page name, then using Sort operator to sort by that new attribute containing the length values.

Hi @s_nektarijevic ,

to add to @kypexin comment: Instead of sort you could use an Aggreate operator to directly get max(len).
