set_layout_graph {flowGraph} | R Documentation

## Determines cell hierarchy layout.

### Description

Determines cell hierarchy layout and returns the X, Y coordinate of each cell population.

### Usage

    set_layout_graph(gr, layout_fun = "layout.reingold.tilford")

### Arguments

`gr` | A list containing data frames `e` and `v`.
`layout_fun` | A string of a function from the `igraph` package that indicates what layout should be used if a cell hierarchy is to be ploted; all such functions have prefix `layout_` e.g. `layout_fun="layout.reingold.tilford"`.

### Value

A list containing data frames `e` and `v`; each data frame contains an X, Y column or coordinate for each node and edge.

### Examples

     no_cores <- 1
     data(fg_data_pos30)
     fg <- flowGraph(fg_data_pos30$count, class=fg_data_pos30$meta$class,
                     prop=FALSE, specenr=FALSE,
                     no_cores=no_cores)

     head(set_layout_graph(fg_get_graph(fg)))
