title: Warning message glmer
body: <p>I am looking at the interaction of 2 fixed variables and 1 random variable. Year has 19 levels and is numeric, beach is a factor and has 4 levels, method is a factor and has 3 levels.
  I am confused on the error messages below. 
  NS1 is my nest success and it is weighted by the total number of eggs.</p>
  
  <pre><code>fit10&lt;-glmer(NS1~0+beach+method+(1|year)+(1+beach*method|year),data=new1,weights=egg_total,family=binomial())
  </code></pre>
  
  <p>Warning messages:</p>
  
  <blockquote>
    <p>1: In eval(expr, envir, enclos) :   non-integer #successes in a
    binomial glm!</p>

    control$checkConv,  :   Model failed to converge: degenerate  Hessian

  <p>EDIT:
  I have changed my code to:</p>
  
  <pre><code>    fit10&lt;-glmer(NS1~0+beach+method+(1|year)+(1|beach/year)+  (1+method|year),data=new1,weights=crawls,family=binomial(),control=glmerControl(optimizer = "Nelder_Mead",optCtrl=list(maxfun=100000)))
  </code></pre>
  
  <p>which only gave me this warning message:</p>
  
  <pre><code>   Warning message:
      In eval(expr, envir, enclos) : non-integer #successes in a binomial glm!
