Radial Plot

Usage

radialplot(values, errors, ...)

# S4 method for class 'numeric,numeric'
radialplot(
  values,
  errors,
  log = TRUE,
  centrality = c("weighted.mean", "mean", "median"),
  bar = FALSE,
  grid = TRUE,
  main = NULL,
  sub = NULL,
  ann = graphics::par("ann"),
  ...
)

# S4 method for class 'CalibratedAges,missing'
radialplot(
  values,
  log = TRUE,
  centrality = c("weighted.mean", "mean", "median"),
  bar = FALSE,
  grid = TRUE,
  main = NULL,
  sub = NULL,
  ann = graphics::par("ann"),
  ...
)

Arguments

values

A numeric vector giving the BP ages or F14C values to be calibrated (conventional ages) or a CalibratedAges object.

errors

A numeric vector giving the errors associated to the values to be calibrated.

...

Further graphical parameters to be passed to graphics::points().

log

A logical scalar: should the z-axis be displayed in logarithmic scale?

centrality

A character string specifying a measure of centrality, used for centering the plot. It must be one of "weighted.mean" (the default), "mean" or "median". Any unambiguous substring can be given.

bar

A logical scalar: should a bar showing the 2-sigma range around the central value be displayed?

grid

A logical scalar: should a grid (originating at \([0,0]\) and stretching to the z-scale) be displayed?

main

A character string giving a main title for the plot.

sub

A character string giving a subtitle for the plot.

ann

A logical scalar: should the default annotation (title and x and y labels) appear on the plot?

Value

radialplot() is called it for its side-effects: it results in a graphic being displayed.

## Data from Bosch et al. 2015
data("ksarakil")

## Radialplot
