clean: Simplify a lvm object

In bozenne/lavaSearch2: Tools for Model Specification in the Latent Variable Framework

Simplify a lvm object

Description

Remove variables with no link.

Usage

clean(x, ...)

## S3 method for class 'lvm'
clean(x, rm.exo = TRUE, rm.endo = TRUE, rm.latent = TRUE, ...)

Arguments

x	lvm-object
...	additional arguments to lower level functions
rm.exo	should exogenous variables with no links be removed from the object?
rm.endo	should endogenous variables with no links be removed from the object?
rm.latent	should latent variables with no links be removed from the object?

Examples

m <- lvm()
m <- regression(m, x=paste0("x",1:5),y="y1")
m <- regression(m, x=paste0("x",1:5),y="y2")
covariance(m) <- y1~y2

cancel(m) <- y1 ~ x1
cancel(m) <- y2 ~ x1
clean(m)

m <- lvm(y1 ~ eta + x1, y2 ~ eta, y3 ~ eta + x2)
latent(m) <- ~eta
clean(m)
m
cancel(m) <- y1 ~ eta
cancel(m) <- y2 ~ eta
cancel(m) <- y3 ~ eta
clean(m)
