This function calculates spatial balance grid cell extent and proportion for the sample frame.
sbcframe(sfobject, nrows = 5, dxdy = TRUE)
An object of class sf that contains the survey frame.
Number of rows (and columns) for the grid of cells. The default is 5.
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.
List containing the following components:
the frame extent for each grid cell
the frame proportion for each grid cell
the grid x-coordinate minimum value
the grid x-coordinate maximum value
the grid y-coordinate minimum value
the grid y-coordinate maximum value
the grid cell x-coordinate increment value
the grid cell y-coordinate increment value
the vector of grid cell x-coordinates
the vector of grid cell y-coordinates
