sbcframe: Calculate Spatial Balance Grid Cell Extent and Proportion for...

In mhweber/spsurvey: Spatial Survey Design and Analysis

Description

This function calculates spatial balance grid cell extent and proportion for the sample frame.

Usage

sbcframe(sfobject, nrows = 5, dxdy = TRUE)

Arguments

sfobject	An object of class sf that contains the survey frame.
nrows	Number of rows (and columns) for the grid of cells. The default is 5.
dxdy	Indicator for equal x-coordinate and y-coordinate grid cell increments, where TRUE means the increments are equal and FALSE means the increments are not equal. The default is TRUE.

Value

List containing the following components:

extent

the frame extent for each grid cell

prop

the frame proportion for each grid cell

xmin

the grid x-coordinate minimum value

xmax

the grid x-coordinate maximum value

ymin

the grid y-coordinate minimum value

ymax

the grid y-coordinate maximum value

dx

the grid cell x-coordinate increment value

dy

the grid cell y-coordinate increment value

xc

the vector of grid cell x-coordinates

yc

the vector of grid cell y-coordinates
