setLink: Set a Link to a Value

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

Set a Link to a Value

Description

Generic interface to set a value to a link in a lvm object.

Usage

setLink(object, ...)

## S3 method for class 'lvm'
setLink(object, var1, var2, value, warnings = FALSE, ...)

Arguments

object	a lvm object.
...	[internal] only used by the generic method.
var1	[character or formula] the exogenous variable of the new link or a formula describing the link to be added to the lvm.
var2	[character] the endogenous variable of the new link. Disregarded if the argument var1 is a formula.
value	[numeric] the value at which the link should be set.
warnings	[logical] should a warning be displayed if the link is not found in the lvm object.

Examples

library(lava)
set.seed(10)

m <- lvm()
regression(m) <- c(y1,y2,y3)~u
regression(m) <- u~x1+x2
latent(m) <- ~u
covariance(m) <- y1 ~ y2

m1 <- setLink(m, y3 ~ u, value = 1)
estimate(m1, lava::sim(m,1e2))
# m1 <- setLink(m, u ~ y3, value = 1)

m2 <- setLink(m, y1 ~ y2, value = 0.5)
estimate(m2, lava::sim(m,1e2))
