plot.EWSmethods {EWSmethods}

Plot an EWSmethods object

Description

A function for visualising the output of uniEWS or multiEWS using ggplot2 inspired figures.

Usage

## S3 method for class 'EWSmethods'
plot(
  x,
  ...,
  y_lab = "Generic indicator name",
  trait_lab = "Generic trait name",
  trait_scale = 1000
)

Arguments

x

An EWSmethods object created by uniEWS or multiEWS

...

Additional arguments to pass to the plotting functions.

y_lab

String label. Labels the abundance y axis.

trait_lab

String label. If trait argument populated in uniEWS or multiEWS, & "trait" supplied in metrics, labels the right side y axis which represents trait values through time.

trait_scale

Numeric value. Scales trait y axis relative to abundance y axis.

Value

A ggplot2 object.

Examples

data(simTransComms)

#Subset the third community prior to the transition

pre_simTransComms <- subset(simTransComms$community3,time < inflection_pt)

#Perform multivariate EWS assessments
roll_ews <- multiEWS(
 data = pre_simTransComms[,2:7],
 method = "rolling",
 winsize = 50)

 #Plot outcome
## Not run: 
 plot(roll_ews)

## End(Not run)

#Perform univariate EWS assessments on
#simulated data with traits

abundance_data <- data.frame(time = seq(1:50),
 abundance = rnorm(50,mean = 20),
 trait = rnorm(50,mean=1,sd=0.25))

trait_ews <- uniEWS(
 data = abundance_data[,1:2],
 metrics = c("ar1","SD","trait"),
 method = "expanding",
 trait = abundance_data[,3],
 burn_in = 10)

#Plot outcome
## Not run: 
 plot(trait_ews, y_lab = "Abundance",
 trait_lab = "Trait value",
 trait_scale = 10)

## End(Not run)
