S4 Class "Transect"

Description

Virtual Class "Transect"

Details

Virtual Class "Transect" is an S4 class detailing a single survey, a single set of transects.

Slots

strata.names

a character vector of the strata names

design

Describes the design algorithm used to create the survey.

samplers

Contains the survey transects

strata.area

The areas of the strata in the design

cov.area

The total areas sampled within each strata. Areas sampled twice are counted twice.

cov.area.polys

The polygons representing the covered area of the survey.

samp.count

Numeric value(s) giving the number of realised transects.

effort.allocation

a vector of probabilities determining how effort is allocated between strata. Effort allocated based on area if left empty.

spacing

determines the spacing of systematic samplers

design.angle

numeric value detailing the angle of the design. Can provide multiple values relating to strata. The use of the angle varies with design, it can be either the angle of the grid of points, the angle of lines or the design axis for the zigzag design.

edge.protocol

character value indicating whether a "plus" sampling or "minus" sampling protocol is used.
