A plotting function for visualizing the model space explored in MiSSEGreedy.
Arguments in `...`

are passed to `plot.igraph`

.

`PlotMisseSpace(x, possible.combos=NULL, arrows.by.weight=FALSE, ...)`

## Arguments

- x
a `misse`

list of model fits obtain from `MiSSEGreedy`

.

- possible.combos
data.frame of parameter combinations to try. See 'Details'.

- arrows.by.weight
a logical indicating whether arrow direction between adjacent model reflects which model has higher support. The default is `FALSE`

which means arrows show direction of model complexity.

- ...
Additional parameters to control the igraph plot. See `plot.igraph`

.

## Details

If the input x is a list of `misse`

fits from MiSSEGreedy then size of the vertices are in proportion
of their AIC weights. If only the “possible.combos” is input, and `x=NULL`

, then the model space
will be plotted but with each vertex having the same size.
