var2dummy: Convert Variable Names to Dummy Variables Names.

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

Convert Variable Names to Dummy Variables Names.

Description

When dealing with categorical variables, the estimate function convert the categorical variables into dummy variables. This function convert a set of variable names to their corresponding name in the model with dummy variables

Usage

var2dummy(object, ...)

## S3 method for class 'list'
var2dummy(object, var, rm.first.factor = TRUE, ...)

## S3 method for class 'lvm'
var2dummy(object, data = NULL, ...)

Arguments

object	a lvm object.
...	[internal] additional arguments to be passed from var2dummy.lvm to var2dummy.list.
var	[character] the variable to be transformed.
rm.first.factor	[logical] should the first level of each categorical variable be ignored?
data	[data.frame] dataset according to which the model should be updated.

Examples

## Not run: 
var2dummy <- lavaSearch2:::var2dummy
var2dummy.list <- lavaSearch2:::var2dummy.list
var2dummy.lvm <- lavaSearch2:::var2dummy.lvm

m <- lvm()
regression(m) <- c(y1,y2,y3)~u
regression(m) <- u ~ X1+X2
var2dummy(m, var = c("X1","X2"))
categorical(m,labels=c("M","F","MF")) <- ~X1
var2dummy(m, var = c("X1","X2"))
categorical(m,labels=c("1","2","3")) <- ~X2
var2dummy(m, var = c("X1","X2"))

## End(Not run)
