latent: Set specifications of a latent variable

In gastonstat/pathdiagram: Basic functions for drawing path diagrams

Description

Use this function to specify the graphic characteristics of a latent variable. The specifications will be used by the function draw to plot latent variables (in a path diagram).

Usage

  latent(label = "latent", x = 0.5, y = 0.5, rx = 0.05,
    ry = 0.05, border = "white", lwd = 2, fill = "#5f8bd7",
    col = "white", cex = 1, vfont = NULL, font = 2,
    family = "sans")

Arguments

label	A character string with the label to be displayed.
x	x-axis coordinate for center of ellipse.
y	y-axis coordinate for center of ellipse.
rx	long radius of ellipse.
ry	short radius of ellipse.
border	color of the border.
lwd	width of border line.
fill	color to fill the ellipse
col	color of the label.
cex	numeric character expansion of the label.
vfont	font family of the label.
font	An integer specifying which font to use for the label. See par
family	The name of a font family for drawing text. Standard values are "serif", "sans" and "mono".

Details

Latent variables are drawn as ellipses using the function plotellipse

Value

An object of class "latent", which is a list with the specified parameters to draw latent variables.
