Hello,
Because there is no root of that function in the interval c(0, 10). Just
like the error message says.

uniroot(function(x) 5*x - 55, c(0, 20))
Why does this instruction fail if the interval is changed?
uniroot(function(x) 5*x - 55, c(0, 10))
Error in uniroot(function(x) 5 * x - 55, c(0, 10)) :
f() values at end points not of opposite sign
