A data frame containing information on the size and shape of secondary sampling units for the comspat function.

Usage

param_tran

Format

A data frame with 16 observations (sampling steps) on the following 2 variables.

Steps.of.scaling

Numeric. Sampling step number

Length.of.plots

Numeric. Length of the sampling unit.

Details

The comspat function requires spatially explicit information. The params argument stores and provides spatially explicit information. The parameter data frame for the grid and transect data (i.e., param_grid and param_tran) are available in the package. The data contains information on the number of scaling steps (Steps.of.scaling column) and the size (the number of primary sampling units to create the length and height of the secondary sampling unit, captured in the Length.of.plots and Height.of. plots columns) of the secondary sampling units. For example, to perform secondary sampling on a grid, the first row of the parameter data set will read 1 for Steps.of.scaling, Length.of.plots and Height.of.plots. If the data was sampled as a "Transect" only the Length.of.plots coordinate is required. If the data was sampled as a "Grid" both Length.of.plots and Height.of.plots are required.

Length.of.plots and Height.of.plots are measured in the number of sampling units.
