Data Science – learn R or Python?

Hi Folks,

I have a query around whether to learn R from scratch or should I leverage my basic python knowledge to extend into Data Science with scikit,numpy ,pandas? So I am bit confused … I am not shy to learn New programming language like R etc bur really need to know who edges out whom in market. Maybe i should learn R too along with Python so  your valuable opinion matters.

            Also i am playing around with IBM’s MessageSight product for Internet of things so interested in REAL Time Streaming Analytics. May be this will help to whether i should choose Python or R?

           So please enlighten me to see the unseen ….cheers and thanks for the help.
