timings


Run times measured on an Intel(R) Xeon(R) CPU X5680 clocked at 3.33 GHz
with 12 MB cache, running RedHat Enterprise Linux, R 3.2.3 and gcc 4.8.5,
using version 0.4 of the <code>wrswoR</code> package.
The data are created by the corresponding scripts in the <code>data_raw</code>
directory.


Includes performance measurements and results of repeated
experiment runs (for correctness checks) for code in the
'wrswoR' package.

timings function

A data frame with 5 columns: <dl>
  <dt><code>prob</code></dt><dd>
    A description of the probability distribution used.
    See <code>data_raw/benchmark.R</code> for details.
  </dd> <dt><code>expr</code></dt><dd>
    Function name without the <code>sample_int_</code> prefix.
  </dd> <dt><code>time</code></dt><dd>
    Run time in nanoseconds, as measured by
    <code><a rd-options="microbenchmark" href="/link/microbenchmark?package=wrswoR.benchmark&version=0.1-1&to=microbenchmark" data-mini-rdoc="microbenchmark::microbenchmark">microbenchmark</a></code>
