integratepdf

Numerically integrate pdf of observed distances over specified ranges

Description

Computes integral of pdf of observed distances over x for each observation. The method of computation depends on argument switches set and the type of detection function.

Usage

integratepdf(
  ddfobj,
  select,
  width,
  int.range,
  standardize = TRUE,
  point = FALSE,
  left = 0,
  doeachint = FALSE
)

Arguments

`ddfobj`	distance detection function specification
`select`	logical vector for selection of data values
`width`	truncation width
`int.range`	integration range matrix; vector is converted to matrix
`standardize`	logical used to decide whether to divide through by the function evaluated at 0
`point`	logical to determine if point count (`TRUE`) or line transect (`FALSE`)
`left`	left truncation width
`doeachint`	calculate each integral numerically

Value

vector of integral values - one for each observation
