Plot method for map layout — plot.mapLayout • antaresViz

This method can be used to visualize the network of an antares study. It generates an interactive map with a visual representaiton of a map layout created with function mapLayout.

# S3 method for mapLayout
plot(
  x,
  colAreas = x$coords$color,
  dataAreas = 1,
  opacityArea = 1,
  areaMaxSize = 30,
  areaMaxHeight = 50,
  areaChartType = c("auto", "bar", "pie", "polar-area", "polar-radius"),
  labelArea = NULL,
  labelMinSize = 8,
  labelMaxSize = 8,
  colLinks = "#CCCCCC",
  sizeLinks = 3,
  opacityLinks = 1,
  dirLinks = 0,
  links = TRUE,
  areas = TRUE,
  tilesURL = defaultTilesURL(),
  preprocess = function(map) {     map },
  width = NULL,
  height = NULL,
  ...
)

Arguments

x	Object created with function `mapLayout`
colAreas	Vector of colors for areas. By default, the colors used in the Antares software are used.
dataAreas	A numeric vector or a numeric matrix that is passed to function `link[addMinicharts]`. A single vector will produce circles with different radius. A matrix will produce bar charts or pie charts or polar charts, depending on the value of `areaChartType`
opacityArea	Opacity of areas. It has to be a numeric vector with values between 0 and 1.
areaMaxSize	Maximal width in pixels of the symbols that represent areas on the map.
areaMaxHeight	Maximal height of bars. Used only if a barchart representation is used.
areaChartType	Type of chart to use to represent areas.
labelArea	Character vector containing labels to display inside areas.
labelMinSize	minimal height of labels.
labelMaxSize	maximal height of labels.
colLinks	Vector of colors for links.
sizeLinks	Line width of the links, in pixels.
opacityLinks	Opacity of the links. It has to be a numeric vector with values between 0 and 1.
dirLinks	Single value or vector indicating the direction of the link. Possible values are 0, -1 and 1. If it equals 0, then links are repsented by a simple line. If it is equal to 1 or -1 it is represented by a line with an arrow pointing respectively the destination and the origin of the link.
links	Should links be drawn on the map ?
areas	Should areas be drawn on the map ?
tilesURL	URL template used to get map tiles. The followign site provides some URLs; https://leaflet-extras.github.io/leaflet-providers/preview/
preprocess	A function that takes as argument a map and that returns a modified version of this map. This parameter can be used to add extra information on a map.
width	Width of the graph expressed in pixels or in percentage of the parent element. For instance "500px" and "100%" are valid values.
height	Height of the graph expressed in pixels or in percentage of the parent element. For instance "500px" and "100%" are valid values.
...	Currently unused.

Value

The function generates an htmlwidget of class leaflet. It can be stored in a variable and modified with package leaflet

Examples

if (FALSE) {
# Read the coordinates of the areas in the Antares interface, then convert it
# in a map layout.
layout <- readLayout()
ml <- mapLayout(layout)

# Save the result for future use
save(ml, file = "ml.rda")

# Plot the network on an interactive map
plot(ml)

# change style
plot(ml, colAreas = gray(0.5), colLinks = "orange")

# Use polar area charts to represent multiple values for each area.
nareas <- nrow(ml$coords)
fakeData <- matrix(runif(nareas * 3), ncol = 3)
plot(ml, sizeAreas = fakeData)

# Store the result in a variable to change it with functions from leaflet 
# package
library(leaflet)

center <- c(mean(ml$coords$x), mean(ml$coords$y))

p <- plot(ml)
p %>% 
  addCircleMarker(center[1], center[2], color = "red", 
                  popup = "I'm the center !")
}
