plot_astro_anchor: Plot proxy record anchored to an astronomical solution

Description

Plot the results of the anchoring the extracted signal to an astronomical solution using which was conducted using the astro_anchor

Usage

plot_astro_anchor(
  astro_solution = NULL,
  proxy_signal = NULL,
  anchor_points = NULL,
  time_dir = TRUE,
  keep_editable = FALSE
)

Value

The output is a set of 2 plots connected by lines The top plot is the proxy record with anchor points on top of it The bottom plot is the astronomical solution The lines connect the anchor points

Arguments

astro_solution

Input is an astronomical solution with with the the proxy record was be anchored to, the input should be a matrix or data frame with the first column being age and the second column should be a insolation/angle/value

proxy_signal

Input is the proxy data set which will which was anchored to an astronomical solution, the input should be a matrix or data frame with the first column being depth/time and the second column should be a proxy value.

anchor_points

Anchor points generated using the astro_anchor function

time_dir

The direction of the proxy record which was assumed during anchoring if time increases with increasing depth/time values (e.g. bore hole data which gets older with increasing depth ) then time_dir should be set to TRUE if time decreases with depth/time values (eg stratospheric logs where 0m is the bottom of the section) then time_dir should be set to FALSE time_dir=TRUE

keep_editable

Keep option to add extra features after plotting Default=FALSE
