Simple plotPrettyGraph function saves to png.

PlotPrettyGraph given inputs from the makeGraph function. adapted from http://is-r.tumblr.com/.

plotPrettyGraph(
  adjacencyMatrix,
  functionToPlot,
  pngfn = tempfile(fileext = ".png"),
  scaleText = 0.5,
  vertexSize = NA,
  figScale = 11,
  layoutmode = "eigen",
  hueval = 0
)

Arguments

adjacencyMatrix	igraph adjacencyMatrix
functionToPlot	igraph node-level graph value e.g. degree, page.rank, etc
pngfn	filename for output png or to screen if NA
scaleText	relative size of text to vertices
vertexSize	cex size of vertices
figScale	the figure will be of square size 2^figScale in pixels
layoutmode	see gplot.layout in sna package
hueval	controls the hue in hsv

Value

no output
