net.plot: Network Plot

In audrey-b/BUGSnet: Bayesian network meta-analyses in compliance with best practice and reporting guidelines

Network Plot

Description

Produces network plot where nodes represent treatments and edges represent direct evidence (e.g an RCT) comparing treatments.

Usage

net.plot(
  data,
  node.scale = 5,
  edge.scale = 2,
  flag = NULL,
  study.counts = FALSE,
  label.offset1 = 0,
  label.offset2 = 0,
  graph.scale = TRUE,
  node.lab.cex = 1,
  edge.lab.cex = 1,
  node.colour = "#f69c54",
  edge.colour = "grey",
  edge.lab.colour = "blue",
  flag.edge.colour = "lightpink",
  layout = "layout_in_circle",
  layout.params = NULL
)

Arguments

data	A BUGSnetData object produced by data.prep().
node.scale	Size of the nodes (default = 5)
edge.scale	Thickness of the edges (default = 2).
flag	Used to highlight direct comparisons to particular treatments (optional). Set this value to treatment(s) of interest and it will highlight, in red, all of the edges going into the specified treatment(s).
study.counts	If TRUE, prints the number of studies on each edge.
label.offset1	Node label offset relative to node. Default = 0.
label.offset2	Additional label offset for nodes close to the x axis. Default = 0.
graph.scale	Whether to make edges and nodes proportionally larger with the number of studies/arms. Default is TRUE.
node.lab.cex	Size of node labels
edge.lab.cex	Size of edge labels
node.colour	Node colour (string)
edge.colour	Edge colour (string)
edge.lab.colour	Edge label colour (string)
flag.edge.colour	Color of flagged edges (string)
layout	Specifies how the nodes should be layed out in the graph. Default is "layout_in_circle". See igraph::layout_ for layout options
layout.params	Additional parameters to be passed to the chosen 'layout' function. See igraph::layout_ for more information

Examples

data(diabetes.sim)

diabetes.slr <- data.prep(
  arm.data = diabetes.sim, 
  varname.t = "Treatment", 
  varname.s = "Study"
)

# use default settings
net.plot(diabetes.slr)

# Highlight all direct comparisons with Placebo. Adjust node and edge size, centre node labels
net.plot(
  data = diabetes.slr, 
  node.scale = 4, 
  edge.scale = 1.5, 
  flag="Placebo", 
  label.offset1 = 0, 
  label.offset2 = 0
)
