    Hi everyone:
    I have a density function f(x|theta)=theta*x^(theta-1),where 0<x<1,0<theta<infinite

I want to pratice on R to find the MLE of this function,here is my code:

    x <- (0:10)/10
f<-function(theta) prod(theta*x^(theta-1)) mle(f)
and r gave me :Error in eval(expr, envir, enclos) : argument is missing, with no default

what mistake I just made?and how to add a constraint of theta>0 in my function.

Great thanks for your time~
