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
