This file is to play with ways to compare proportion of habitat used v available.
There are two matrices: one for availability (Habitat Availability.csv) and one for use (Habitat Use.csv). They are in Gondek, Matt -> Data _ Gondek
hu = read.csv("Habitat Use.csv", header=T)
ha = read.csv("Habitat Availability.csv", header=T)

## The analysis was carried out with 7 animals and 7 habitat types
## 1. Test of the habitat selection:
## randomisation test
## Lambda P
## 0.005747109 0.150000000
