Subject Re: Mahout and lucence and data formats
Date Thu, 18 Nov 2010 21:15:25 GMT
Ted ,
Thanks for your email. I understand that R reads values in text format.
I have a problem with dumping out data from Mahout.
The data spit out by apache mahout and its format and conversion to a text
format is my main concern.
Not the R's side of the story.

Thanks for your help
Shivani
