[Rsiena-help] ego x alter error message

[Lewis, Kevin]

greetings,

recently i attempted to run a network/behavior co-evolution model using the latest version of R, and the latest version of RSiena from r-forge. the network is undirected, and i included the "ego x alter" selection effect for the behavioral variable. i received the following error message:

> results <- siena07(mymodel, data=mydata, effects=myeff, batch=FALSE, verbose=TRUE)
Loading Tcl/Tk interface ... done
Error in initializeFRAN(z, x, data, effects, prevAns, initC, profileData = profileData,  :
  Unexpected effect name: egoXAlt

i had no trouble with this model using Siena version 3, so i am wondering if this is just a bug in the ego x alter effect for undirected networks in RSiena? any help would be appreciated! many thanks,

-kevin
