hpdi function

Computes the highest posterior density interval (HPDI) for calibrated dates

hpdi(
  x,
  credMass = 0.95,
  asList = TRUE,
  calendar = "BP",
  sep = "|",
  pdigits = 3
)

Arguments

• x: A CalDates class object.
• credMass: Interval probability mass
• asList: Logical variable determining whether the output should be a list (TRUE) or a character vector (FALSE). Default is TRUE
• calendar: Whether daes should be reported in cal BP ("BP") or in BCAD ("BCAD"). Default is 'BP'. Ignored when "asList=TRUE".
• sep: character string to separate date ranges. Default is '|'. Ignored when "asList==TRUE".
• pdigits: indicate the number of decimal places for reporting probabilities. Default is 3. Ignored when "asList==TRUE".

Returns

A list of matrices with HPDI ranges and associated probabilities in cal BP. Note that the sum of the probability mass will be only approximately equal to the argument credMass.

Examples

x <- calibrate(c(2000,3050,2950),c(35,20,20))
hpdi(x)
hpdi(x,asList=FALSE,calendar='BCAD')
