Help: namespace ‘lavaan’ is not available and has been replaced?

[Armin Pircher Verdorfer]

Hi, folks

I've got a weired problem with installing lavaan. No matter which R version ( for mac) I use, I 'm constantly getting the following warning in R Studio:

Warning in install.packages :
  package ‘lavaan’ is not available (for R version X.X.X)

When I check directly in R, I get the following warning:

Warning: namespace ‘lavaan’ is not available and has been replaced
by .GlobalEnv when processing object ‘fit1’

I never got this problem before and it all started after installing the "apaTables" package.

I have tried everything (e.g., I reinstalled R and R Studio) but the problem keeps driving me nuts.

Any help is GREATLY appreciated as I have spent the whole morning trying to fix this problem and tracking down forums for help but everything has proved unhelpful.

cheers, Armin

What does sessionInfo() tell you about your R environment?

I reinstalled an old R version again (3.2.1). the session info command yields the following result:

Hi Armin,

lavaan requires a newer R.

Depends:

R (≥ 3.4)

https://cran.r-project.org/web/packages/lavaan/index.html

So, I would recommend downloading the latest R and giving it another shot.

[Armin Pircher Verdorfer]

Unfortunately, the problem persists...no matter wich R version I use (I now use 3.3.3 which is the most recent version for my mac system).

I'm pretty sure though this issue has nothing to do with lavaan, but with my R environment...

[Christopher D Desjardins]

lavaan depends on R version 3.4 or higher. At version 3.3.3, you can't use the newer lavaan. I am guessing a package tried to install a newer version of lavaan and now you've lost the older version of lavaan.

If you don't need the newest features, you could download a tarball from here: https://cran.r-project.org/src/contrib/Archive/lavaan/ and install it from source. I would recommend downloading lavaan_0.5-23.1097.tar.gz (since it predates 3.3.3)

1. Download the tarball to your Downloads folder.

2. Open a Terminal and type: cd ~/Downloads

3. Type: R CMD INSTALL lavaan_0.5-23.1097.tar.gz

This should install. You might need to install Xcode but I don't think lavaan uses C, C++, or fortran (or something else that needs to be compiled).

You may also be able to install a newer version of R from source (https://cran.r-project.org/doc/manuals/r-release/R-admin.html#Installing-R-under-Unix_002dalikes).

Update: I think the problem started when I was installing the apaTables package. R Studio asked my "Do you want to install from sources the package which needs compilation?" 

I said yes, silly me! Any idea how Ican get rid of this whole mess and how I can restore R to the state it was yesterday? (just uninstalling and reinstalling it did'nt work so far)

Dear Lavaan community. 

I am just starting to use Lavaan and I cannot install the package. I have tried several options commented in the group. 

I updated R version to the latest one and I just tried to upload lavaan from source, I still get this message

"  ERROR: dependencies 'mnormt', 'quadprog' are not available for package 'lavaan'
* removing 'C:/Users/s1900308/Documents/R/win-library/3.6/lavaan'
Warning in install.packages :
  installation of package ‘C:/Users/s1900308/Downloads/lavaan_0.5-23.1097.tar.gz’ had non-zero exit status "

Any other step I should take?

You seem to still use R 3.6. Remove it, so that you are using the latest
version (4.0.2).

Yves.
