In RAMpath: Structural Equation Modeling Using the Reticular Action Model (RAM) Notation

Generate a vector field plot based on the bivariate lcsm

Description

Generate a vector field plot based on the bivariate lcsm

Usage

ramVF(ramout, ylim, xlim, ninterval=10, scale=.1, length=.25, 
scatter=TRUE, n=20, alpha=.95, ...)

Arguments

ramout	Output from the ramBLCS function
ylim	Range of y data, for example, c(0,80) from 0 to 80
xlim	Range of x data, for example, c(0,80) from 0 to 80
ninterval	Number of intervals for plotting. The default is 10.
scale	Time interval to calculate vector fields.
length	The length of arrows to plot
scatter	Whether to plot the data points
n	The number of data points to be plotted
alpha	The confidence level to calculate the ellipse
...	Options for plot and arrows function.
