Hi,

I am a novice R user, who is committed to learning OpenMx for structural equation modeling for my research in psychology. I have been using the reference manual as a guide for setting up the syntax for the measurement model of my analysis. I have 19 manifest variables, and 7 latent constructs, for which I would like to obtain general fit indices, parameter estimates and modification indices. I tried to run the analysis using raw data that has less than 5% missingness. The following error messages were produced:

Error: unexpected ',' in "values=c(1,1,1),"

Error: unexpected ',' in "2", "ipv1", "ipv3", "ipv2", "ferc", "eerc", "cvs", "cvc", "cvp", "anx1", "anx2", "anx3", "pts1", "pts2", "pts3", "agg1", "agg2", "agg3"), latentVars = c("abuse", "partner", "community", "e"

Error: unexpected input in "anx1", "anx2", "anx3", "pts1", "pts2", "pts3", "agg1", "agg2", "agg3"), arrows=2, free=TRUE, values=c(1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1,1), labels=c("e1","e2","e3","e4","e5","e6", "e7","e8","

The syntax I used is pasted below:

manifests<- c("fm1", "fm2", "ipv1", "ipv3", "ipv2", "ferc", "eerc", "cvs", "cvc", "cvp", "anx1", "anx2", "anx3", "pts1", "pts2", "pts3", "agg1", "agg2", "agg3")

I would really appreciate any help.

Thanks in advance!
