Slope graph for ggplot2 — ggslope • HohgantR

Creates a slope graph ideal to use when computing changes in one or more indicators between waves of a survey or other time series data with a low number of periods.

Usage

ggslope(
  data,
  x,
  y,
  group,
  DataLabel = NULL,
  title = "No title given",
  subtitle = "No subtitle given",
  caption = "No caption given",
  LineThickness = 1,
  LineColor = "ByGroup",
  DataTextSize = 2.5,
  DataTextColor = "black",
  DataLabelPadding = 0.05,
  DataLabelLineSize = 0,
  DataLabelFillColor = "#f5f5f2",
  WiderLabels = FALSE,
  ReverseYAxis = FALSE,
  ReverseXAxis = FALSE,
  RemoveMissing = TRUE
)
