Plot multiple dates

Description

Plot multiple radiocarbon dates.

Usage

multiplot(
  x,
  type = "d",
  calendar = "BP",
  HPD = FALSE,
  credMass = 0.95,
  decreasing = NULL,
  label = TRUE,
  label.pos = 0.5,
  label.offset = 0,
  xlim = NULL,
  xlab = NA,
  ylab = NA,
  col.fill = "grey50",
  col.fill2 = "grey82",
  col.line = "black",
  lwd = 1,
  cex.id = 1,
  cex.lab = 1,
  cex.axis = 1,
  ydisp = FALSE,
  gapFactor = 0.2,
  rescale = FALSE
)

Arguments

`x`	A CalDates class object with length > 1.
`type`	Whether the calibrated dates are displayed as distributions (`'d'`) or as horizontal bars (`'b'`) spanning the HPD interval. Default is `'d'`.
`calendar`	Either `'BP'` or `'BCAD'`. Indicate whether the calibrated date should be displayed in BP or BC/AD. Default is `'BP'`.
`HPD`	Logical value indicating whether intervals of higher posterior density should be displayed. Default is FALSE.
`credMass`	A numerical value indicating the size of the higher posterior density interval. Default is 0.95.
`decreasing`	Whether dates should be plotted with decreasing order of median calibrated date (i.e. old to new; TRUE) or increasing order (i.e. new to old; FALSE). If set to NULL the dates plotted in the supplied order. Default is NULL
`label`	Whether the ID of each date should be displayed. Default is TRUE.
`label.pos`	Relative position of the label in relation to the calibrated distribution expressed in quantiles. Default is 0.5 (median).
`label.offset`	Horrizontal offset of label position in number of years. Default is 0.
`xlim`	the x limits of the plot. In BP or in BC/AD depending on the choice of the parameter `calender`. Notice that if BC/AD is selected BC ages should have a minus sign (e.g. `c(-5000,200)` for 5000 BC to 200 AD).
`xlab`	(optional) Label for the x axis. If unspecified the default setting will be applied ("Year BP" or "Year BC/AD").
`ylab`	(optional) Label for the y axis.
`col.fill`	A vector of primary fill color for the calibrated date distribution. Default is 'grey50'.
`col.fill2`	A vector of secondary secondary colour fill color for the calibrated date distribution, used for regions outside the higher posterior interval. Ignored when `HPD=FALSE`. Default is 'grey82'.
`col.line`	A vector of line color (ignored when `type` is set to `'d'`. Default is 1.
`lwd`	Line width (ignored when `type` is set to `'d'`). Default is 1.
`cex.id`	The magnification to be used the date labels relative to the current setting of cex. Default is adjusted to 1.
`cex.lab`	The magnification to be used for x and y labels relative to the current setting of cex. Default is adjusted to 1.
`cex.axis`	The magnification to be used for axis annotation relative to the current setting of cex. Default is adjusted to 1.
`ydisp`	Whether the y axis should be displayed. Ignored when `type` is set to `'b'`. Default is FALSE
`gapFactor`	Defines spacing between calibrated dates (when `type` is set to `'d'`) or the distance between the lines and the labels (when `type` is set to `'b'`) as proportion of individual y-axis ranges. Default is 0.2.
`rescale`	Whether probability distributions should be rescaled (applicable only when `type` is set to `'d'`, default is FALSE).

Examples

data("emedyd")
tellaswad = subset(emedyd,SiteName=='Tell Aswad')
x = calibrate(tellaswad$CRA,tellaswad$Error,ids=tellaswad$LabID)
multiplot(x,HPD=TRUE,decreasing=TRUE,label=FALSE,gapFactor = 0.1)
multiplot(x,type='b',calendar='BCAD',cex.id = 0.5,lwd=2,gapFactor = 0.5)
