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?

Michel

One suggestion is to download

One suggestion is to download the OpenMx pre-release and run your script. We have improved the error messages for algebras for OpenMx 1.1. I would recommend not relying on the pre-release to publish results (yet). We are in the process of testing the pre-releases, and the pre-release r1527 is out-of-date with respect to the source code repository.

Oops. Nevermind, we have not

Oops. Nevermind, we have not added context information to that error situation yet. Probably better to just attach your script to a forum post.

so i just added the script, i

so i just added the script, i dont think however this will quickly solve the problem. Am i right to suspect the algebra styatements are involved in this error?

I improved the error message

I improved the error message in our source code repository, so now it prints out the name of the algebra in which the error occurs. The error is the expression "CpathM %*% + CpathM" in the algebra CvDOS. Same error occurs in CvSibOS.
