plotDanube: Plot Danube River Flow Data

Description

Plotting function to visualize the river flow data from the danube dataset. Requires ggplot2 to be installed.

Usage

plotDanube(
  stationIndices = NULL,
  graph = NULL,
  directed = NULL,
  plotStations = TRUE,
  plotConnections = TRUE,
  labelStations = FALSE,
  returnGGPlot = FALSE,
  useStationVolume = FALSE,
  useConnectionVolume = FALSE,
  mapCountries = c("Germany"),
  vertexColors = NULL,
  vertexShapes = NULL,
  edgeColors = NULL,
  xyRatio = NULL,
  clipMap = 1.2,
  useLatex = FALSE,
  edgeAlpha = 0.2
)
plotDanubeIGraph(
  stationIndices = NULL,
  graph = NULL,
  directed = NULL,
  labelStations = TRUE,
  vertexColors = NULL,
  vertexShapes = NULL,
  edgeColors = NULL,
  ...
)

Arguments

stationIndices

Logical or numerical vector, indicating the stations to be plotted.

graph

An igraph::graph object or NULL to use the flow graph.

directed

Logical. Whether to consider the flow graph as directed.

plotStations

Logical. Whether to plot the stations.

plotConnections

Logical. Whether to plot the connections.

labelStations

Logical. Whether to label stations.

returnGGPlot

If TRUE, a ggplot2::ggplot object is returned and not plotted immediately.

useStationVolume

Logical. Whether to indicate flow volume at a station by circle size.

useConnectionVolume

Logical. Whether to indicate flow volume on a connection by line width.

mapCountries

Which country borders to show using ggplot2::map_data('world', mapCountries).

vertexColors

Vector with color information for vertices.

vertexShapes

Vector with shape information for vertices.

edgeColors

Vector with color information for edges.

xyRatio

Approximate X-Y-ratio (w.r.t. distance on the ground) of the area shown in the plot.

clipMap

Logical or numeric scalar. Whether to ignore the map image when determining the axis limits of the plot. If it is a positive scalar, the plot limits are extended by that factor.

useLatex

Whether to format numbers etc. as latex code (useful when plotting to tikz).

edgeAlpha

Numeric scalar between 0 and 1. The alpha value to be used when plotting edges/connections.

...

Passed through to igraph::plot.igraph.

Details

The values of vertexColors, vertexShapes, and edgeColors are interpreted differently by ggplot2::geom_point/ggplot2::geom_segment and igraph::plot.igraph().

plotDanube uses a combination of ggplot2 functions to plot the graph.

plotDanubeIGraph uses igraph::plot.igraph to plot the graph.
