R packages for Structural Equation Model: SEM with R

Structural Equation Model (SEM) was first examined by a software called LISREL. Then, SEM has been mainly run by several proprietary software i.e., Mplus, AMOS, EQS, SAS and a new version of Stata (v.12).

However, you may also run SEM with a great but free software like R.

To the best of my knowledge, there are now four active packages that you can use to fit SEM. Here they are:

Main Packages (for fitting SEM models) 

  1. sem (John Fox, 2006):The first R package for SEM ” fit by maximum likelihood assuming multinormality, and single-equation estimation for observed-variable models by two-stage least.squares.” It was also the first package I tried to run SEM in R. Thanks to a very quick response from Prof.Fox on my question I emailed him.
    See Example of ‘sem’ package here.
  2. OpenMx (Boker et al, 2011)
    A very active package that “is free and open source software for use with R that allows estimation of a wide variety of advanced multivariate statistical models.” contributed by experts in R and SEM.
    See Example of ‘OpenMx’ package here.
  3. lavaan (Yves Rosseel, 2012)
    A promising package for SEM. Its command language is similar to those of Mplus. Hence it is perhaps the most user-friendly package for SEM to date.
    See Example of ‘lavaan’ package here.

  4. semPLS (Armin Monecke, 2012)
    Fitting Structural Equation Model Using Partial Least Squares
    See: CRAN link, JSS paper
  5. plspm (Gaston Sanchez, 2012)
    R package dedicated to Partial Least Squares (PLS) methods (CRAN,
    by Gaston Sanchez and Laura Trinchera
    A corresponding book titled “PLS Path Modeling with R” can be downloaded here.
My paper in useR! 2011 has evaluated R packages vs. Proprietary software i.e., AMOS & Lisrel.

Today (30 May 2012), I gladly found that there are also complementary packages for SEM in R as follows.

    I tend to agree with you, lavaan is extremely user friendly, but sem seems to offer a greater variety of test and much needed capabilities that are not (yet?) available in lavaan. Let us encourage the developers of lavaan to extend their package to emulate AMOS and sem more closely.

    • Dear Faan,

      lavaan is really a light and hope. I just met the developer at the useR! 2011 and I could say that there’s a lot more to come from lavaan next version. Also a new version of sem package, with more compact code, will be also released soon!

    form of antenna can be adjusted and is more efficient in receiving
    digital television signals. Mant940 indoor/outdoor hdtv antenna Unless your STB is decoding an HD signal, or even the signal is via another
    HD source directly into your HDTV it’s most likely not
    planning to be in HD. You just need a implies of selecting up and transmitting the signal, it can be
    feasible to make use of a wireless Tv set antenna in place in the built-in Wi-Fi
    receiver. Diy hdtv antenna cardboard One major requirement is the fact that this antenna can operate while using different broadcast

    Mounting your antenna inside the attic is possible, but it really is best
    that you happen to be aware in the pitfalls related to
    this form of configuration. To get the radio signal,
    the receiver posseses an antenna which is located in the range of signal.
