[Ipmpack-users] Problems with makeGrowthObj

[Jordan Golubov]

Dear All,

Just dowloaded IPMpack. I had trouble make my growth object and tried
the one in the vignette and also failed with the same error. I am
pasting the error message below

> dff <- generateData()
> gr1 <- makeGrowthObj(dataf = dff, Formula = sizeNext~size)
Error in makeGrowthObj(dataf = dff, Formula = sizeNext ~ size) :
  unused argument(s) (Formula = sizeNext ~ size)

Thanks
