Usage

as_events(from, ...)

as_phases(from, ...)

as_rece(from, ...)

# S4 method for matrix
as_events(from, calendar = c("BP", "CE", "b2k"), iteration = NULL)

# S4 method for data.frame
as_events(from, calendar = c("BP", "CE", "b2k"), iteration = NULL)

# S4 method for matrix
as_phases(
  from,
  start = seq(from = 1, to = ncol(from), by = 2),
  stop = start + 1,
  names = NULL,
  calendar = c("BP", "CE", "b2k"),
  iteration = NULL
)

# S4 method for data.frame
as_phases(
  from,

  stop = start + 1,
  names = NULL,
  calendar = c("BP", "CE", "b2k"),
  iteration = NULL
)

# S4 method for matrix
as_rece(from, calendar = c("BP", "CE", "b2k"), age = 1)

Arguments

from

from An object to be coerced.

...

Currently not used.

calendar

A character string specifying the chronological scale It must be one of "BP" (the default), "CE" or "b2k".

iteration

A length-one numeric vector specifying the index of the iteration column.

start

An integer vector specifying the index of the columns corresponding to the beginning of the phases. If missing, every other column is used starting from the first column (after deleting the iteration column, if any).

stop

An integer vector specifying the index of the columns corresponding to the end of the phases. If missing, every other column is used starting from the second column (after deleting the iteration column, if any).

names

A character vector giving the names of the phases.

age

A length-one numeric vector specifying the index of the age column.

Value

An MCMC object.
