Generate Graph Layout
This function generates plot coordinates for each variable in a graph that does not have them already. To this end, the well-known “Spring” layout algorithm is used. Note that this is a stochastic algorithm, so the generated layout will be different every time (which also means that you can try several times until you find a decent layout).
graphLayout(x, method = "spring")
x |
the input graph, of any type. |
method |
the layout method; currently, only |
the same graph as x
but with layout coordinates added.
## Generate a layout for the M-bias graph and plot it plot( graphLayout( dagitty( "dag { X <- U1 -> M <- U2 -> Y } " ) ) ) ## Plot larger graph and abbreviate its variable names. plot( getExample("Shrier"), abbreviate.names=TRUE )
