I am trying to learn Python and/or R. When I do a google search I get lots of information that becomes overwhelming. For someone that uses either 1 of these tools on a regular basis, how should I go about learning it. Can someone give me ideas on which book to read first, second, third and so on, or it could be something like which video to watch first etc. I have basic programming knowledge but want to start analyzing more data. Any Python/R gurus in SF Bay area?
