Plots a graph in R.

lav_plotinfo_rgraph.Rd

Creates a graph in R showing a simple diagram of the model.

Usage

lav_plotinfo_rgraph(plotinfo,
                    sloped.labels = TRUE,
                    outfile = "",
                    addgrid = TRUE,
                    mlovcolors = c("lightgreen", "lightblue"),
                    lightness = 1,
                    italic = TRUE,
                    auto.subscript = TRUE
                   )

Arguments

plotinfo

A plotinfo structure as returned from lav_plotinfo_positions.

sloped.labels

Logical, sloped labels above (or under) the edges.

outfile

Character string naming the file to store the diagram in PNG or NA to show the plot in R.

addgrid

Logical, add a grid with indicated 'positions' to the graph?

mlovcolors

Array of two colors for distinguishing ov nodes with same name between the levels in a multilevel model.

lightness

A scalar factor to modify the distances between nodes.

italic

Are labels to be in italic font? Attention: The switch to an italic font will only be possible if the label value isn't an expression!

auto.subscript

Logical, see lav_label_code.

Value

NULL (invisible)
