### Solving basic programming problems

The assignment for the first few weeks of the course is to document your progress solving some programming problems in R. You will be editing an .rmd file on your webpage, and submitting the link to your page each week. Here is a brief tutorial showing you how to get started.

### Another sample problem

In this screen cast we solve the following problem: Generate 100 random numbers between 1 to 100. Find only the numbers that are greater than 50, then add up those selected numbers. The general goal is to see some examples of using variables, logic, and loops to write a script, and finally to put the algorithm into a more general function.

### Fork a repo and make a pull request

As part of the assignment due Feb 25th, you will be forking a repository to your github account, cloning it to your computer, adding some code to the .Rmd files in the repository, then pushing those changes back to your version of the repository, and finally making a pull-request that those changes be incoporated into the original repository. Here is a screencast showing how to do these steps.
