View source: R/plot_delta_tracers.R

Description

Plot the posterior distribution of magnification or enrichment for specified tracers

Usage

1
plot_delta_tracers(myfit, mydata, trac_names, transfo = list(NULL))

Arguments

myfit

a fit as returned by fit_escroc

mydata

a list as returned by prepare_data

trac_names

a character or vector list containing the tracers to be plotted

transfo

either NULL or a list of functions, on per tracer, to carry transformation if required

Value

a list of the same length as trac_names with a ggplot
