boxplotPEs: Boxplot of percentage errors for the given data from dataset

In svcuonghvktqs/FORA: A package for time sereis forecast accuracy evaluation

Description

This function returns box and whisker plots of percentage errors for the given data from dataset for different methods

Usage

boxplotPEs(df, useLogs = FALSE, notch = FALSE, limits = NULL,
  showOutliers = NULL, ...)

Arguments

df	A data frame containing columns "actual" and "forecast" and "method".
useLogs	logical. If useLogs==TRUE the resulting box and whisker plotted in logarithmic scales. If FALSE the resulting box and whisker plotted in scales by default.
notch	logical. If the notch==TRUE, a notch is drawn in each side of the boxes.
limits	The minimum and maximum values on the axis APE. If xlim is NULL, minimum and maximum values are calculated based on given data.
showOutliers	If showOutliers is NA, the outliers are not drawn.
...	Other undocumented arguments.
