agread(filename, layoutType="dot", layout=TRUE)

Arguments

graph

An object of class Ragraph

filename

layoutType

character(1) specifying the format of the input file. must be one of graphvizCapabilities()$layoutTypes.

Examples

V <- letters[1:10]
M <- 1:4

z <- agopen(g1, "foo", layout=FALSE) ## default layoutType 'dot'
file <- tempfile()
agwrite(z, file)


## supported input types
graphvizCapabilities()$layoutTypes
g2 <- agread(file, layout=TRUE)
if (interactive())
   plot(g2)
