"Error extracting SUMMARY OF DATA in output file" when running 3-level SEM

[pehkawn]

I've been attempting to extract data from the output of an empty three-level model in Mplus. However, running mplusModeler() or readModels() returns the error message:

Error extracting SUMMARY OF DATA in output file: model0.out

<simpleError in extractValue(pattern = "^\\s*Average cluster size\\s*", section,     filename, type = "dec"): More than one match found for parameter: ^\s*Average cluster size\s*
  model0.out>

I tried defining the same model with only one cluster, and the error message is gone. I can therefore only assume this has something to do with the model have more than one cluster.

I'm having a simular issue with a cross-nested model. I get almost the same error message:

<simpleError in extractValue(pattern = "^\sNumber of clusters\s", section, filename, type = "int"): More than one match found for parameter: ^\sNumber of clusters\s sim.out>

Hi there,

I just pushed a commit that now parses the summary of data section for crossclassified models. I tested this against Mplus User's Guide example 9.24, which is the only cross-classified output I personally have. If you'd like me to test your specific case, please upload your .out file here (you'll have to label it as .txt for Github to accept it).

Re: the threelevel output above, @pehkawn, I couldn't replicate the issue. Could you upload your output file here?

I should also clarify that these 'simpleError' messages by the package do not reflect complete failure of parsing, but a localized error in parsing a certain section. So, your outputs may otherwise be intact and perfectly usable.

Sorry for my late reply. Here it is. (.txt suffix added in order to be able to upload GitHub.)
