In this tutorial, I'm going to show you how to scrape data tables of SNPs from Snpedia, and how to use that data to check to see if you have those SNPs in your own genome. I'm also going to show you how to save that information for future use.

In this tutorial, we will go over how to manually create bins in hist() that create probabilities and bars for each individual level of a discreet variable. While we’re at it, we are going to use this example to cover some other useful operations for data analysis in R including: how to extract an element of a list into a vector, creating a new variable of cumulative probabilities, recoding probabilities as percentages and percentiles, creating a function, and how to merge data sets together.
