Hi all, I'm new here. I'm an MPH student at Georgia State and am interning for a research firm that specializes in oncology-related clinical trials here in Georgia. I've been given as of yet unreleased county-specific data for breast cancer by stage when diagnosed, and I've been told to find relative risks per county and see which counties have the most advanced stages on average when diagnosed. My variables are County, In Situ, Localized, Regional, Distant, and Unknown/Unstaged. How do I manipulate County (which is a string variable because of the county names) so that I can work with it, and what sort of analysis should I run once I do? Thank you.
