lavaan_cov {lavaanExtra}

Extract relevant covariance/correlation indices from lavaan model

Description

Extract relevant covariance/correlation indices from lavaan lavaan::parameterEstimates and lavaan::standardizedsolution.

Usage

lavaan_cov(fit, nice_table = FALSE, ...)

lavaan_cor(fit, nice_table = FALSE, ...)

Arguments

fit

lavaan fit object to extract covariance indices from

nice_table

Logical, whether to print the table as a rempsyc::nice_table as well as print the reference values at the bottom of the table.

...

Arguments to be passed to rempsyc::nice_table

Value

A dataframe of covariances/correlation, including the covaried variables, the covariance/correlation, and corresponding p-value.

Functions

• lavaan_cor(): Shortcut for lavaan_cov(fit, estimate = "r")

Examples

x <- paste0("x", 1:9)
(latent <- list(
  visual = x[1:3],
  textual = x[4:6],
  speed = x[7:9]
))

(regression <- list(
  ageyr = c("visual", "textual", "speed"),
  grade = c("visual", "textual", "speed")
))

(covariance <- list(speed = "textual", ageyr = "grade"))

HS.model <- write_lavaan(
  regression = regression, covariance = covariance,
  latent = latent, label = TRUE
)
cat(HS.model)

library(lavaan)
fit <- sem(HS.model, data = HolzingerSwineford1939)
lavaan_cov(fit)
