title: How many bootstraps does rfsrc in the R package randomforestsrc peform?
body: <p>Does anyone know how many bootstraps or subsamples a standard call to rfsrc performs?</p>
  
  <pre><code>rf1&lt;-rfsrc(Surv(time,status)~., data=myTable)
  </code></pre>
  
  <p>Also <code>rf1$err.rate</code> which is described as "cumulative OOB error rate" for me at the above settings is a vector of length 1000, with 999 element being <code>NA</code>and only the last element is an error rate (between 0 and 0.5). Is that the expected behaviour? Is this last value the average error of all bootstraps?</p>
  
  <p>Update: I have found a setting <code>block.size</code>, which regulates how many OOB error rates out of the 1000 are returned. If you set it to e.g. 10, every thenth OOB error rate is filled. Hower what I am still not sure about is on how many bootstraps each of these error rates is calculated. Is each simply one error rate from a single bootstrap or subsample or is it somehow averaged?</p>
