Projects

Programming Assignment #1 - Air Pollution:

For this first programming assignment you will write three functions that are meant to interact with dataset that accompanies this assignment. The dataset is contained in the zip file specdata.zip.

Programming Assignment #2 - Caching the Inverse of a Matrix:

Matrix inversion is usually a costly computation and there may be some benefit to caching the inverse of a matrix rather than computing it repeatedly (there are also alternatives to matrix inversion that we will not discuss here). Your assignment is to write a pair of functions that cache the inverse of a matrix.

Programming Assignment #3 - Hospital Quality:

See the file "rprog-doc-ProgAssignment3.pdf" inside the Assignment 3 directory for more information about this assignment.
