Resampling Stats (http://www.resample.com) is an add-in for
running randomization tests in Excel worksheets. The workflow is (1) to define
a statistic of interest that can be calculated from a data table, (2) to
randomize rows ad/or columns of a data table to simulate a null hypothesis
and (3) and to score the value of the statistic from many randomizations. The
relative frequency distribution of the statistic in the simulations is then
used to infer the probability of the observed value be generated by the null
process (probability of Type I error). This package intends to translate this
logic for R for teaching purposes. Keeping the original workflow is favored over
performance.

The ant colonies live in the hollow
trunk of Cecropia and can detect and expel leaf-chewing insects.
To test if this response is more intense in young leaves, drops of extract of smashed young and old leaves
were poured in two neighbor leaves of the same plant. After 7 minutes the number of recruited ants in each leaf was recorded.
