[Ipmpack-users] sensParams problem

[Kimmy Kellett]

Hey all,
I am trying to use sensParams on my IPM, and am getting the error message
"Error in fecObj at offspringRel$coeff :
  object of type 'S4' is not subsettable"

My fecObj is : fvS<-makeFecObj(SIPM,Formula=(fec2~size),Family="binomial",fecConstants
= data.frame(seedlingsPerRep=2.5),
                offspringSplitter=data.frame(continuous=0,Seedling=1),

)

and the offspringRE1 slot says:
Slot "offspringRel":
<S4 Type Object>
attr(,".S3Class")
[1] "lm"


Anyone know how to make it NOT an S4 type object?? Thanks!!
