Matt,
Some time back I didn't like the uniroot restriction either so I wrote a short
function manyroots that breaks an interval into many shorter intervals and
looks for a single root in each of them. This function is NOT guaranteed to
find all roots in an interval even if you specify many
Hi all,
This is probably a blindingly obvious question: Why does it matter in
the uniroot function whether the f() values at the end points that you
supply are of the same sign?
For example:
f - function(x,y) {y-x^2+1}
#this gives a warning
uniroot(f,interval=c(-5,5),y=0)
Error in uniroot(f,

Plot some graphs.
Think about the *name* of the function
