Missing values introduced when running multigroup alignment model on simulated data

[jenniferdguay]

Hi,

I'm trying to run a multigroup alignment model with different oblique rotations. However, when running the model on simulated data, I get an error that the data has 1 missing value for each group even though the data has been generated with no missing values.

The simulated data looks something like this:

The code used to estimate the model is written as:

alignment.mdl <- mplusObject(
  TITLE =     "Run multigroup alignment;",
  VARIABLE =  "USEVARIABLES = group x1-x10; GROUPING =  group(2);",
  MODEL= "F1-F2 BY x1-x10(*1);",
  ANALYSIS =  "ROTATION = oblimin; alignment = fixed;",
  OUTPUT = "align;",
  rdata = simout$data  
)
alignment.fit <- mplusModeler(alignment.mdl, modelout = "alignment.inp", run=T)

The following message is printed in the console:

No PROPORTION OF DATA PRESENT sections found within COVARIANCE COVERAGE OF DATA output.
Warning message:
In readModels(target = outfile, quiet = quiet) : NAs introduced by coercion

and I get this error in the Mplus output file:

How can I fix this issue?

Many thanks!
