Sample size estimation using the odds ratio in a case-control study

I wrote a short tutorial on how to use an odds ratio to estimate the sample size needed for a case-control study.

Logistic regression in R

I wrote a tutorial on how to construct logistic regression models in R. This tutorial was published on RPubs (link). I go through the use of the glm() command to perform a crude logistic regression model and a multivariable logistic regression model. The data (diabetes.csv) that I used for the motivating example is located here.
