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?
