Dear Gaters,
Recently, I began using R for regression and structural equation modeling analyses. However, I could not create the covariance matrix in R using lavaan's lower2full() function.
For example, each time I run the code, "example.cor
Hello Tobi,
It seem that R didn't find the function so 3 possibilities :
1) You didn't install "lavaan" package
2) You didn't load "lavaan" library
3) Both ! ^^
Please find here the script where the function work correctly :
> install.packages('lavaan')
> library(lavaan)
This is lavaan 0.5-17
lavaan is BETA software! Please report any bugs.
Message d'avis :
le package ‘lavaan’ a été compilé avec la version R 3.0.3
> example.cor example.cor
[,1] [,2] [,3] [,4]
[1,] 1.00 0.85 0.84 0.68
[2,] 0.85 1.00 0.61 0.59
[3,] 0.84 0.61 1.00 0.41
[4,] 0.68 0.59 0.41 1.00
Each time you want to use function from package you need :
1) install the package
2) install the library
PS : I don't know this package and these function... So I can't tell you if those are reliable or not.
Best regards.
Cyril,
Thank you!!! I followed the instructions and got the issue resolved!
Moreover, I first uninstalled a few packages (i.e. foreign, pequod, psych, lavaan.survey, xlsx, and lavaan) which I had used before encountering this error. In addition, rather going through the "Tools" drop-down menu option to install the packages, I used your code.
Your contribution is highly appreciated.
Best,
Tobi.
Additional question: do you know why the error message below appears whenever I run the 'lower2full' program? Thanks!
Warning message:
'lower2full' is deprecated.
Use 'lav_matrix_lower2full' instead.
See help("Deprecated") and help("lavaan-deprecated").
It's warning message coming from the author of the package.
I guess he/she tell you that the function is not the last version and mays contain few error. Please look at the help text as suggested and see if others updated functions do the job you need.
Your issues are more about R use than the functions themself...
As R is free and powerful I encourage people to use it, 'cause maybe oneday you'll develop it ! ;-)
That's why you are welcome to ask me question (in private message, I think it's better) if you need further help on R programmation.
Regards
