Hmm. Try setting extendInt="yes" in the call to uniroot. You should also
look at the help page for uniroot. help(uniroot) May give you a clue. It's

roots on the interval or has an

I`m Mark and I do my PhD in biology. I try using R to calculate a population
growth rate of animals grown on different types of food. Our workgroup has a
R-skript to do so, but sadly nobody, who knows how this works. I`ve never
used R before, but got some stuff figure
