Extract Root Decay, New Root Production, and No-Change Roots (only 'RootDetector' images)

Extract Root Decay, New Root Production, and No-Change Roots (only 'RootDetector' images)

Usage

turnover_dpc(
  img,
  product.layer = 2,
  decay.layer = 1,
  blur.capture = 0.95,
  im.return = FALSE,
  include.virtualroots = FALSE
)

Arguments

img

SpatRaster with three layers for production, decay, and stagnation

product.layer

Integer indicating the production layer index (1-3)

decay.layer

Integer indicating the decay & tape layer index (1-3)

blur.capture

Threshold for pixel inclusion (0-1). Default: 0.95

im.return

Logical: return images instead of values? Default: FALSE

include.virtualroots

Logical: consider all roots present at any timepoint? Default: FALSE

Value

If im.return = FALSE: tibble with pixel sums and ratios If im.return = TRUE: list of SpatRaster layers for tape, constant, production, and decay

Examples

data(TurnoverDPC_data)
img = terra::rast(TurnoverDPC_data)
DPCs = turnover_dpc(img = img, im.return = FALSE)
