initVar: Normalize var1 and var2

In bozenne/lava.reduce: Latent Variable Models with linear predictor

Description

Convert var1 and var2 from formula or covariance to character

Usage

initVar_link(var1, var2, repVar1 = FALSE, format = "list",
  Slink = lava.options()$symbols[1], Scov = lava.options()$symbols[2])

initVar_links(var1, format = "list")

Arguments

var1	a character indicating the endogeneous variable or a formula
var2	an optional character indicating the exogeneous variable
repVar1	should var1 be duplicated to match var2 length. Only active if format = "list".
format	should the name of the variable be return (format = "list"), a vector of character formula ("txt.formula") or a list of formula ("formula")
Slink	the symbol for regression link
Scov	the symbol for covariance link

Details

See test file test/testthat/test-Reduce.R for examples

Examples

initVar_link(y ~ x1)
initVar_link("y ~ x1")
initVar_link(y ~ x1 + x2)
initVar_link("y ~ x1 + x2")
initVar_link(y ~ x1 + x2, repVar1 = TRUE)
initVar_link(y ~ x1 + x2, repVar1 = TRUE, format = "formula")
initVar_link(y ~ x1 + x2, repVar1 = TRUE, format = "txt.formula")
initVar_link("y", "x1", format = "formula")

initVar_link("y ~ x1:0|1")


initVar_links(y ~ x1)
initVar_links("y ~ x1")
initVar_links(c("y ~ x1","y~ x2"))
initVar_links(c(y ~ x1,y ~ x2))
initVar_links(c("y ~ x1","y~ x2"), format = "formula")
initVar_links(c(y ~ x1,y ~ x2), format = "formula")
initVar_links(c("y ~ x1","y~ x2"), format = "txt.formula")
initVar_links(c(y ~ x1,y ~ x2), format = "txt.formula")
