R help - Aug 2012 - What package to use to calculate odds ratio and the confidence interval?

Hi list,
I am trying to calculate the sensitivity, specificity, and odds ratio(and
confidence interval).
Say, my data looks like this

42.53, 37.56, 40.51, 32.67, 38.19, 81.74, 41.55, 68.94, 59, 63, 54.13,
48.85, 50.46, 51.78

Is there any packages in R that does this?  Espeically the odds ratio
confidence interval.

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.
