R Programming and the New Epidemiologists

When I started working as an epidemiologist at a state health department, one of the most often used tools was the Microsoft Office Suite of programs. I used Excel for data analysis and visualization, Access to create and manage databases, Power Point to create presentations, and Word to create reports.

EpiRen’s Journal Club: Firearm-Related Hospitalization and Risk of Bad Stuff Thereafter, in Washington State, Between 2006 and 2011
