Plots Accumulated Local Effects for ERF — plot

Plots the Accumulated Local Effects (ALE) from an ERF object

plot_ALE(
  ALE,
  xquantiles = c(0.025, 0.975),
  yquantiles = c(0.1, 0.5, 0.9),
  name,
  cex.axis = 1,
  cex.lab = 1,
  rug = TRUE,
  rug.col = "gray50",
  rug.tick = 0.02,
  rug.lwd = 0.5,
  rug.alpha = 0.2,
  rug.max = 1000,
  gap.axis = NA,
  alt.labels = NULL
)

Arguments

ALE: an ALE object for a given variable; indexed as a list for full functionality
xquantiles: lower and upper quantile bounds to limit x values to
yquantiles: lower, middle, and upper quantiles to plot the confidence interval around the ALE predictions
name: the x-axis label of the variable; self-supplied if indexed as a list
cex.axis: the cex of the axis
cex.lab: the cex of the labels
rug: logical for turning the rug plot on/off (defaults to table values for class=='factor')
rug.col: color of rug ticks
rug.tick: length of rug ticks
rug.lwd: width of rug ticks
rug.alpha: transparency of rug ticks
rug.max: maximum number of ticks to plot (useful for big data)

Value

A plot of the ALEs

Examples

#run an ERF with 10 RFs and 
ens_rf_ex <- ens_random_forests(df=simData$samples, var="obs", covariates=grep("cov", colnames(simData$samples),value=T), save=FALSE, cores=1)
#> rounding n.forests to the nearest one

ALE_df <- ALE_fn(ens_rf_ex, save=FALSE)
#> Error in ALE_fn(ens_rf_ex, save = FALSE): unused argument (save = FALSE)

plot_ALE(ALE_df[1])
#> Error in eval(expr, envir, enclos): object 'ALE_df' not found
