Integral of pdf of distances — gstdint • mrds

Computes the integral of distpdf with scale=1 (stdint=TRUE) or specified scale (stdint=FALSE).

Usage

gstdint(
  x,
  ddfobj,
  index = NULL,
  select = NULL,
  width,
  standardize = TRUE,
  point = FALSE,
  stdint = TRUE,
  doeachint = FALSE,
  left = left
)

Arguments

x: lower, upper value for integration
ddfobj: distance detection function specification
index: specific data row index
select: logical vector for selection of data values
width: truncation width
standardize: if TRUE, divide through by the function evaluated at 0
point: logical to determine if point (TRUE) or line transect(FALSE)
stdint: if TRUE, scale=1 otherwise specified scale used
doeachint: if TRUE perform integration using integrate
left: left truncation width

Value

vector of integral values of detection function

Note

This is an internal function that is not intended to be invoked directly.
