Hi Peter,

I wrote a package called rHVDM. It does not do quite what you want,  
but you might want to check it out. Basically if you know some  
targets of a transcription factor, It will deduce the activation  
profile of that transcription factor and then using this information,  
it will predict which other genes might be targets, all based on the  
kind of data you have. Multiple transcription dependency is in  
project (and subject of current research elsewhere too).
