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