gstdint: Integral of pdf of distances

In mrds: Mark-Recapture Distance Sampling

Integral of pdf of distances

Description

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.
