Hi,

I'm experiencing the same problems.. Installed the package DRM yestarday..
first couple of runs it worked..
I closed down R and now I want to do the same code again and I get the
error:

Error in drm(TotDmShoot ~ DAP, data = DATA, fct = gompGrowth.2()) : 
  Cluster not specified. Use e.g. y ~ x + cluster(id)

What do I have to do to fix this? 

Thank you,

Jelle
