You need to provide more information than you have. The odds of something happening is the probability of it happening divided by (1-probability). To calculate the odds ratio, you need to have odds for two different groups. I suspect you need to get some local statistical assistance on these concepts before you will get much help on R packages and functions. Dan Daniel J.
