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

is to be called on the result of file input.

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())
