combine/permute a list from a file or pipe
Description:
combo -[pc]
Perform combinatoric transformations on a list of elements
separated by newline. Input may be a filename, or '-' to
read from STDIN. Combinations/Permutations are written to
STDOUT, one per line, with elements separated by tab.
Options:
-p permute list; this is the default behavior
-c combine list; this parameter requires an integer value
for how many of the list elements should be included
in the combination

Shanon-Weiner Calculator
Description:
Give this script a data matrix in a comma separated document of abundances of different species (each species is a column, each plot is a row), and it will output a file which will not only have your original data, but also an additional column for total abundance of all species, and the Shanon-Weiner Diversity Index.

Leslie/Lefkovitch Matrix Modelling Metrics
Description:
Give this script a population matrix and an initial population vector. The script will then graph the population trajectory, both for each age/stage class and the population as a whole. It will also show the long term population growth rate the stable age distribution, the weighted reproductive value and the sensitivity and elasticity matrices and return the long term growth rate for future usage.
