mplus2lavaan not working

[Georgi Yankov]

I am trying to convert MPlus syntax to lavaan syntax with the mplus2lavaan function but I get the error below. My MPlus data and .inp files are in the same directory as the R syntax file. I also tried with other .inp like http://statmodel.com/userguide/chap5/ex5.1.inp

> bestmodel <- mplus2lavaan("BestEstimation.inp", run = F)

Error in mplus2lavaan.modelSyntax(sections$model) :

  mplus2lavaan.modelSyntax syntax argument should be a single string, not a vector

Any help is much appreciated!

Dear Georgi,

I have the same question.

In my case, I used the attached MPlus code and I got this error

Error in sub("^([^@]+)(@[\\d-.]+)?$", "\\2", v_post, perl = TRUE) :
  invalid regular expression '^([^@]+)(@[\d-.]+)?$'
In addition: Warning message:
In sub("^([^@]+)(@[\\d-.]+)?$", "\\2", v_post, perl = TRUE) :
  PCRE pattern compilation error
        'invalid range in character class'
        at '-.]+)?$'

Any help would be really appreciated!

C.

Confirmed. I will alert the maintainer of the mplus2lavaan() function.
