title: retain several best models during model dredging in R
body: <p>Is there a way to retain the best models, for example, within two Alkaike Information Criterion (AIC) units of the best fitting model, during a model dredging approach in R? I am using the <code>glmulti</code> package, which returns the AIC of the best models, but does not allow visualizing the models associated with those values.</p>
  
  <p>Thanks in advance.</p>
  
  <p>Here is my example (data <a href="https://www.dropbox.com/s/v6ywo32fv9ihp54/gameresults.csv?dl=0" rel="nofollow noreferrer">here</a>):</p>
  
  <pre><code>results &lt;- read.csv("gameresults.csv")
  require(glmulti)
  M &lt;- glmulti(result~speed*svl*tailsize*strategy,
               data=results, name = "glmulti.analysis", 
               intercept = TRUE, marginality = FALSE,
               level = 2, minsize = 0, maxsize = -1, minK = 0, maxK = -1,
               fitfunction = Multinom, method = "h", crit = "aic",
               confsetsize = 100,includeobjects=TRUE)
  
  summary(M)
  </code></pre>
