Description

Usage

data(nminer)

Format

A data frame with 31 observations on the following 9 variables.

Miners

the presence or absence of noisy miners; a numeric vector with levels 1 (present) or 0 (absent)

Eucs

Area

the area in hectares of contiguous remnant patch of vegetation in which the transect was located; a numeric vector

Grazed

whether the area was grazed or not; a numeric vector with levels 0 (grazed) or 1 (not grazed)

Shrubs

whether shrubs were present in the transect or not; a numeric vector with levels 1 (shrubs present) or 0 (shrubs not present)

Bulokes
