[Rsiena-help] Error in createEffects("behaviorBipartiteObjective2", varname, names(xx$depvars)[j], : empty effect group

[Julia Brennecke]

Dear all,

 

I am trying to run a co-evolution model for a bipartite network and I keep
getting an error message after using the getEffects command: "Error in
createEffects("behaviorBipartiteObjective2", varname, names(xx$depvars)[j],
:   empty effect group".

 

I am using RSIENA version 1.0.12.146 (16 05 2011) R-forge revision: 146.

 

When I run the same model on an older computer (Windows XP as compared to
Windows 7 on the new one) using R-SIENA version 1.0.11.125 (07 11 2010)
R-forge revision: 125, I don't get this error message and the estimation
works fine.

 

So I am wondering if this is a bug in the newer version of SIENA and someone
could fix it for me? Or am I missing something else, maybe in my script (see
below)?

 

Any help would be highly appreciated! Thanks a lot!

 

Best,

Julia

 

 

R-Script:

network <- sienaNet(array(c(network.data.w1, network.data.w2,
network.data.w3, network.data.w4), dim=c(451, 57, 4)), "bipartite",
nodeSet=c("individuals", "companies"))

individuals <- sienaNodeSet(451, nodeSetName="individuals")

companies <- sienaNodeSet(57, nodeSetName="companies")

behavior.data <- as.matrix(read.table("behavior_2006-2009_451.dat"))

behavior.data [behavior.data %in% c(-999)] <- NA

behavior <- sienaNet( behavior.data, type = "behavior", nodeSet
='individuals')

myCoEvolutionData <- sienaDataCreate( network, behavior,
nodeSets=list(individuals, companies))

myCoEvolutionEff <- getEffects( myCoEvolutionData )
