Dear Andre,
some people would be happy to assist you, but your code fragment is
incomplete, so diagnosing your problem was impossible. Please read the
posting guide and provide a minimum reproducible example.
Furthermore I wonder why you use dede and not ode, and why sum() with
empty parenthesis (that returns always zero).

I have the following differential equations and return list:
dCgd.dt = -kad*y[1]-kgd*y[1] # PK model equation gut d
dCld.dt= kad*y[1]-rhyd-rmetd #pk model equation liver d
dCgl.dt = -kal*y2[1]-kgl*y2[1] # PK model equation gut l
dCll.dt= kal*y2[1]-rhyl-rmetl #pk model equation liver l
# PK model equation
return(list(c(dCgd.dt,dCld.dt,dCgl.dt,dCll.dt),c(massbalance=sum())))
}
For the DDE solve I have :
out = dede(y=y0,times=times,func=model.LIDR,parms=parms)
This gives me the following error:
Error in func(time, state, parms, ...) : object 'p' not found
Can someone explain this error and its remedy?
