Welcome

Hello and welcome to the R for healthcare website. This site contains an ever growing set of training materials relevant for the use of the R language by people working in and around healthcare.

This set of resources is something that healthcare analysts will find particularly useful as it will provide you with the skills required to undertake and automate those analytics tasks you would normally do in spreadsheet programmes such as Excel.
