In pbs-assess/PACea: An R package of Pacific ecosystem information to help facilitate an ecosystem approach to fisheries management

Plot the red/blue style of anomaly plot, linearly interpolating to make smooth (needed when crossing x-axis); internal function called from 'plot-pacea_index()'.

Description

Adapted from https://stackoverflow.com/questions/74902499/shading-below-line-graph-in-r/74903305#74903305 and interpolated.

Usage

plot_red_blue(obj_lub, value, xlab, ylab, type, ...)

Arguments

obj_lub	obj a 'pacea_index' object, which is a time series, with a date column that is the lubridate 'date' class.
value	which column of 'obj' to plot
xlab	x-axis label
ylab	y-axis label, the default is an attribute of the 'pacea_index' object.
type	usual argument for 'plot()'
...	optional arguments passed onto 'plot()'. Note that the x-axis is constructed using a lubridate 'date' object, so 'xlim' needs to be a 'date' object (see example).

Value

plot of time series
