plot.pkgDepGraph: Plots a package dependency graph.

Description

Plots a package dependency graph.

Usage

## S3 method for class 'pkgDepGraph':
plot(x, pkgsToHighlight,
  main = "Package dependency graph", legendPosVertex = c(-1, -1),
  legendPosEdge = c(1, -1), shape = "circle", vertex.size = 8, cex = 1,
  ...)

Arguments

x

pkgDepGraph object

pkgsToHighlight

Optional character vector with names of package to hightlight. If missing, defaults to packages used in original call to makeDepGraph

main

Title of plot

legendPosVertex

Numeric vector of length 2, indicating (x, y) position of vertex legend. Both values should be in the range [-1; 1]. If NULL, the vertex legend is not displayed.

legendPosEdge

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.plotting. Could be "none", "circle", "square", ...

vertex.size

Size of vertex shape. See igraph.plotting

cex

Vertex label size.

Examples

tags <- "chron"

# Plot using defaults
dg <- makeDepGraph(tags, includeBasePkgs=FALSE, suggests=TRUE, enhances=TRUE)

set.seed(42); 
plot(dg)

# Move edge legend to top left
set.seed(42); 
plot(dg, legendPosEdge=c(-1, 1))

# Change font size and shape size
set.seed(42); 
plot(dg, legendPosEdge=c(-1, 1), vertex.size=20,  cex=0.5)


# Move vertex legend to top right
set.seed(42); 
plot(dg, legendPosEdge=c(-1, 1), legendPosVertex=c(1, 1), vertex.size=20,  cex=0.5)
