Plot calibrated radiocarbon dates — plot.c14

Plots each element of a cal vector as a separate calendar probability distribution. Use par(mfrow) or par(mfcol) to arrange multiple plots.

Usage

# S3 method for class 'c14_cal'
plot(
  x,
  ...,
  max.plot = 20,
  resolution = NULL,
  fixed_xlim = FALSE,
  show_curve = TRUE
)

Arguments

x: A cal vector of calibrated radiocarbon dates.
...: Additional arguments passed to plot.default().
max.plot: Maximum number of plots to generate. A warning is issued if length(x) > max.plot and only the first max.plot elements will be plotted. Default: 20.
resolution: Resolution of the age grid in years. If NULL (default), automatically calculated to produce approximately 500 points across the age range for smooth curves.
fixed_xlim: Logical. If TRUE, all plots share the same x-axis range (calculated from all dates). If FALSE (default), each plot uses its own age range focused on that specific date.
show_curve: Logical. If TRUE (default), plot the calibration curve as the main plot with the probability distribution overlaid on the right y-axis. If FALSE, only show the probability distribution.

Value

Invisibly returns NULL. Called for its side effect of generating plots.

Examples

x <- cal(c(1000, 2000, 3000), c(30, 40, 50), IntCal20)
plot(x)




# Arrange multiple plots
par(mfrow = c(2, 2))
plot(x)
dev.off()
#> null device 
#>           1 

# Use same fixed x axis limits for all plots
plot(x, fixed_xlim = TRUE)

# Hide calibration curve
plot(x[1], show_curve = FALSE)
