[Rsiena-help] ego x alter error message

[Ruth M. Ripley]

Dear Kevin,

It looks like an error in the shortName. The directed network version is 
called egoXaltX: you could try changing the shortName on the relevant row 
in your effects object to this.

Please let me know if this works. I will do a proper fix when I get a 
moment.

Regards,

Ruth
