R Datalicious

R is calling me.  Anyhow, I’m trying to learn R.  I think R is very powerful, because it has features that allow you to collect data in various ways.  With R, you can also easily analyze data and make charts, graphs, and whatnot.  I’m a newbie in R, and so I may not be able to fully appreciate R.  I’m a newbie in R, and so I don’t know how to express how powerful R is to you.  Nonetheless, I know a few things so far.

Here is one example among many of how I understand R could be used by you.  With R, you can install Rvest package to easily collect data from the Internet (i.e., websites).  Note:  Data don’t have to come from the Internet.  It’s possible to use R to collect data and then store the data into MySQL database.  It is also possible that the data in MySQL can also be converted back into appropriate data formats in which R would be able to utilize.  Marrying MySQL and R together, it’s possible to enlarge the data collection scale by using R, and using R to format data in various manners.  (My newbie speak, because you may know of a more elegant way of going about using R in this specific manner.)

Anyhow, to scratch the surface of R and see how powerful R can be, just check out the two videos right after the break.  (These YouTube videos are not mine, because I embed them from other YouTube’s user-generated content authors.)  Enjoy!
