In exact2x2: Exact Tests and Confidence Intervals for 2x2 Tables

## Test the E+M option
## Test is proposed in Lloyd (2008, Aust. N.Z. J. Stat 50(4), 329-345)
## This script reproduces some results from Table 1
### the T rows (top is one-sided, bottom is two-sided)
## and the E+M column: The p-value results are 0.02518 (one-sided)  and 0.03681 (two-sided)
