Ant_data.count: Ant data with incidence counts

In JohnsonHsieh/ChaoEntropy: Statistical package 'ChaoEntropy'

Description

Species “incidence counts” for ant data provided by Longino et al. (2002). The ant data which used malaise traps method is collected in a tropical rain forest of Costa Rica. In the ant data set presented 455 species occurrences are distributed among 62 samples with 103 species observed.

Usage

data(Ant_data.count)

Format

a numerical matrix or a data frame of two columns. The first column is the frequency j=1, 2...; and the second column is incidence counts (Qj).

	...	...
	19	2
	20	1
	29	1
