gstdint

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.
