R is a very powerful and flexible program, even with its default installation.…The beauty of R, though, is it can go so much further than its base version by…adding packages or bundles of code that add functionality to R. At the moment,…the Comprehensive R Archive Network or CRAN package repository lists over 4000…packages for R, all of which can be freely downloaded and installed.…The creativity and functionality of these packages is astounding, leading many…people such as myself to tell others that R can do anything.…
In this movie, I want to show you how to find out about packages, how to install…them, and how to use them in R.…The first thing to do is to find out about packages that are available.…On the bottom right of the screen here, this is one of the nice things about…RStudio, is you have a list of packages that are already available.…We start from the bootstrap functions under boot, to classification, and it goes…all the way down to the utilities.…These are ones that are installed, but it doesn't mean that they're loaded at the moment.…
The course continues with examples on how to create charts and plots, check statistical assumptions and the reliability of your data, look for data outliers, and use other data analysis tools. Finally, learn how to get charts and tables out of R and share your results with presentations and web pages.
