Plots a package dependency graph.

Description

Plots a package dependency graph.

Usage

## S3 method for class 'pkgDepGraph'
plot(
  x,
  pkgsToHighlight,
  main = paste(attr(x, "pkgs"), collapse = ", "),
  legendPosition = c(-1.2, -1),
  shape = "circle",
  vertex.size = 8,
  cex = 1,
  ...
)

Arguments

x	Object to plot
pkgsToHighlight	Optional character vector with names of package to highlight. If missing, defaults to packages used in original call to makeDepGraph()
main	Title of plot
legendPosition	Numeric vector of length 2, indicating (x, y) position of edge legend. Both values should be in the range ⁠[-1; 1]⁠. If NULL, the edge legend is not displayed.
shape	Shape of edge. See igraph::igraph.plotting(). Could be "none", "circle", "square", ...
vertex.size	Size of vertex shape. igraph::igraph.plotting()
cex	Vertex label size.
...	Ignored

} else {
  pdb <- cranJuly2014

if (interactive()) {
  dg <- makeDepGraph(tags, availPkgs = pdb  , includeBasePkgs = FALSE,
                     suggests = TRUE, enhances = TRUE)
  
  set.seed(43);
  plot(dg)
  
  
  # Move edge legend to top left
  set.seed(42);
  plot(dg, legendPosition = c(-1, 1))
  
  # Change font size and shape size
  set.seed(42);
  plot(dg, legendPosition = c(-1, 1), vertex.size = 20,  cex = 0.5)
  
  
  # Move vertex legend to top right
  set.seed(42);
  plot(dg, legendPosition = c(1, 1), vertex.size = 20,  cex = 0.5)
}
