plot.stackCalSPD: Plot a stack of SPDs

In rcarbon: Calibration and Analysis of Radiocarbon Dates

Plot a stack of SPDs

Description

Visualises multiple SPDs grouped as a stackCalSPD object.

Usage

## S3 method for class 'stackCalSPD'
plot(
  x,
  type = "stacked",
  calendar = "BP",
  spdnormalised = FALSE,
  rescale = FALSE,
  runm = NA,
  xlim = NA,
  ylim = NA,
  xaxt = "s",
  yaxt = "s",
  gapFactor = 0.2,
  col.fill = NA,
  col.line = NA,
  lwd.obs = 1,
  lty.obs = 1,
  cex.lab = 1,
  cex.axis = cex.lab,
  legend = TRUE,
  legend.arg = NULL,
  ylab = NA,
  ymargin = 1.1,
  rnd = 2,
  ...
)

Arguments

x	A stackCalSPD class object. Result of stackspd function.
type	How to display the SPDs.Current options are 'stacked','lines', ''proportion'. and 'multipanel'. Default is 'stacked'.
calendar	Either 'BP' or 'BCAD'. Indicate whether the calibrated date should be displayed in BP or BC/AD. Default is 'BP'.
spdnormalised	A logical variable indicating whether the total probability mass of the SPDs are normalised to sum to unity. Default is FALSE.
rescale	A logical variable indicating whether the summed probabilities values should be rescaled to range 0 to 1. Default is FALSE.Notice that this is different from setting spdnormalised to TRUE.
runm	A number indicating the window size of the moving average to smooth the SPD. If set to NA no moving average is applied. Default is NA
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).
ylim	the y limits of the plot.
xaxt	Whether the x-axis tick marks should be displayed (xaxt='s', default) or not (xaxt='n').
yaxt	Whether the y-axis tick marks should be displayed (xaxt='s', default) or not (xaxt='n').
gapFactor	Defines spacing between SPDs as proportion of the y-axis range for multipanel plots. Default is 0.2.
col.fill	Vector of fill color for the observed SPDs. The default color scheme is based on the Dark2 pallette of RColorBrewer package.
col.line	Line colour for the observed SPDs.The default color scheme is based on the Dark2 palette of RColorBrewer package.
lwd.obs	Line width for the observed SPDs. Default is 1.
lty.obs	Line type for the observed SPDs. Default is 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.
legend	Whether legend needs to be displayed. Item names will be retrieved from the values supplied in the argument group in stackspd. Default is TRUE.
legend.arg	list of additional arguments to pass to legend; names of the list are used as argument names. Only used if legend is set to TRUE. If supplied legend position must be given (e.g. legend.arg=list(x='bottomright').
ylab	a title for the y axis
ymargin	multiplier for the maximum value on ylim range. Default is 1.1.
rnd	integer indicating the number of decimal places to be displayed in the y-axis for when type is set "multitype".
...	Additional arguments affecting the plot.

Details

The display order of the SPDs is given by the factor levels of the user-supplied group argument in the stackspd() function.

bins = binPrep(sites=emedyd$SiteName, ages=emedyd$CRA,h=100)
res = stackspd(x=x,timeRange=c(16000,8000),bins=bins,group=emedyd$Region)
plot(res,type='stacked')
plot(res,type='lines')
plot(res,type='proportion')
plot(res,type='multipanel')
