growthTrendR (version 0.2.1)

plot_scale: plot median of ring width of the target site and its neighbours

Description

This function plots the time series and the geographical distribution of the median ring-width measurements to contrast the target site with its neighbouring sites.

Usage

plot_scale(dt.scale)

Value

A named list with two ggplot objects showing the contrast between the target site and its neighboring sites:

plot.year

A time-series plot of median ring width by year.

plot.ll

A spatial plot showing the geographic location of the sites, with point size proportional to the magnitude of site-level ring-width measurements.

Arguments

dt.scale

a table with class "cfs_scale", resulting from function CFS_scale()
