plot_delta_tracers: Plot Magnification / enrichment

In Irstea/escroc: EscrocR: a R package implementing the models ESCROC and EscroPath

Plot Magnification / enrichment

Description

Plot the posterior distribution of magnification or enrichment for specified tracers

Usage

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

Examples

#importing data
data(signature_data)
data(prior_diet_matrix)
data(LOQ)
data(prior_signature_data)
prior_delta <- data.frame(tracer=c("X15N","X13C"),mean=c(3,0),sd=c(1,1))

#check that everything is ok
mydata <- prepare_data(prior_diet_matrix,signature_data,
LOQ,prior_signature_data,prior_delta)

#build the model
mymodel <- building_model(mydata)

#fit the model
myresults <- fit_escroc(mydata, mymodel)

#a function to compute TMF ()
transfo <- function (x) 10^x
#plot diet
print(plot_delta_tracers(myresults,mydata,"FOSA",list(transfo)))
