fieldAUC: Area Under the Curve

In OpenDroneMap/FIELDimageR: A Tool to Analyze Orthomosaic Images From Agricultural Field Trials

Area Under the Curve

Description

Calculate the area under the curve given by vectors of xy-coordinates.

Usage

fieldAUC(
  data,
  trait,
  keep.columns = c("NAME", "ROW", "RANGE"),
  method = "trapezoid",
  x.start = 0,
  y.start = 0,
  frame = "long"
)

Arguments

data	data table from fieldInfo.
trait	one or more traits to be evaluated.
keep.columns	columns names to be maintained in the output dataset.
method	the type of interpolation. Can be "trapezoid" (default), "step", "linear" or "spline". More information on ??DescTools::AUC.
x.start	value of x to start the AUC (default is 0 days after planting).
y.start	value of y to start the AUC (default is 0).
frame	format of output data. "long" is used for AUC values on the 1st column and traits ID on the2nd column. While "wide" is for objects with dimension n \times m where traits must be in columns and plots/sample in rows.

Value

A list with a data frame with values by plot and experimental field image with format stack.
