model "does not contain a RAM objective function"
Hi,
I'm having some trouble and have been getting an error message that reads:
"Error: The RAM model 'MZ' does not contain a RAM objective function."
What has me perplexed is that I specify what OpenMx should take into account when evaluating the model (for both groups in a BG study):
mxFIMLObjective(covariance="R", means="M", dimnames=manifests, thresholds="expThresholds")
mxAlgebra(expression=MZ.objective + DZ.objective, name="minus2sumll" ),
mxAlgebraObjective("minus2sumll")
Thank you for any insight.

Loading the snowfall Package
Hi All,
I am not sure that I should post this question here or on a more general R discussion board, but here goes.
I am trying to use the snowfall package with OpenMx to use the independent = TRUE function in the mxModel command.
I am able to load the snowfall package, but when I try sfInit(parallel=T, cpus=2) the computer is fed into an infinite loop.
The first time that this happened, Windows asked for special permission to go through the Firewall (which I allowed).

dumbfounded (or dumb) on error message
perplexed over this:
> thisOMxModel <- mxRun(thisOMxModel)
Running testModel
Error in substituteOperators(as.list(retval)) :
internal error -3 in R_decompress1
In addition: Warning message:
In substituteOperators(as.list(retval)) :
restarting interrupted promise evaluation
to get the MxModel, go to:
http://psych.colorado.edu/~carey/OpenMxGUI/weirdErrorMessage.php
everything appears normal. e.g.,
> class(thisOMxModel$MZf@data@observed$Neglect1)
[1] "ordered" "factor"
> class(thisOMxModel$MZf@data@observed$Neglect2)
[1] "ordered" "factor"

How to report your error: Attach the SCRIPT if possible
Help is much easier to provide if you
1. clearly state the error (quote it from the R output)
2. give the steps to reproduce
3. attach the script that generates the error
(can this please be made sticky so it sticks at the top of the list?)

Error in FUN(X[[2L]], ...) : Could not find function with name + and 1 arguments
Running NucTwFam
Error in FUN(X[[2L]], ...) :
Could not find function with name + and 1 arguments
So it would appear from this error I am summing a matrixobject and empty space (hence the could not find a function for one sided summing???) in one of my mxAlgebra functions.
However I have extensively checked my code for a "+" in an maAlgebra function lead by or trailed by a non matrix object or just whitespace. I could not find such a occurence.
I am running OpenMX 1.0.6 in R 2.11
Any sugestions?

abnormally error
Hi, everyone.
I constructed a Cholesky ACE model. When I drop parameters, one submodel (after mxRun()) showed this error:
The job for model 'AE_Cholesky' exited abnormally with the error message: Objective function returned an infinite value.
How can I deal with it? (Other submodels of similar type which dropped different parameters did run.)

Error crashed parallel run
32-bit Windows box running 4 cores; got the same error under R 2.11 and 2.12.1 and OpenMx 1.0.4, 1.0.5 and 1.0.6. Error does not replicate on Mac OS X 10.6.6.
Simulation study with 10 independent submodels, each submodel containing two dependent submodels. The error, in response to running model called 'Full':
Running Full
Error in do.call("fun", lapply(args, enquote)) :
could not find function "fun"

BootstrapParallel error
Hi (Michael)
When I run models/nightly/BootstrapParallelNightly.R
I get:
> modelResults <- mxRun(topModel, silent=TRUE, suppressWarnings=F)
Error in checkForRemoteErrors(val) :
5000 nodes produced errors; first error: unused argument(s) (useOptimizer)
Has there been a change which affects this argument?
Cheers
Mike

R forced closed due to non pd cov matrix
Code as below. I think it is due to a non positive definite covariance input. When this is fixed, all is fine.
A pop -up says R for windows GUI front end has stopped working.
require(OpenMx)
varnames<-c("BIC1","SSC1","BIC2","SSC2");
dataMZ<-dataDZ<-matrix(diag(1,4),nrow=4,ncol=4,dimnames=list(varnames,varnames));
dataDZ[1,2]<-dataDZ[2,1]<-1.2;
p<-2;
pstar<-p*(p+1)/2;
diagind<-(diag(p)==1);
nMZ<-84;
nDZ<-33;
varnames<-c("BIC1","SSC1","BIC2","SSC2");
LA<-mxMatrix(type="Lower",nrow=p,ncol=p,free=T,values=0,
label=paste("a",1:pstar,sep=""),name="LA");

Error in .subset(x, j) : invalid subscript type 'list'
Hello, not sure this is the best place for this question, but here goes.
I have a growth curve and I'm using the age at assessment as a definition variable in the factor loadings. There is missing data, both in the observed variables and the definition variables. It's an ACE twin model. The script is pasted below.
I am getting an error message I've never seen before:
------begin output-------
growthMalesFit <- mxRun(growthMales)
Running growthMales
Error in .subset(x, j) : invalid subscript type 'list'
------end output--------
Can anyone explain? Thanks for your time!
