What is the meaning of include.lowest in reclassify raster package [r]
<p>Given the definition of open internal (does not include end points) and closed interval (includes end points), it's easy to understand the <code>right</code> argument in <code>reclassify</code>. But I am confused on the <code>include.lowest</code>argument. It mentions </p>

<blockquote>
  <p>indicating if a value equal to the lowest value in rcl (or highest
  value in the second column, for right = FALSE) should be included</p>
</blockquote>

<p>the lowest value in rcl would be the first value, which according to <code>right</code> is not included by default, so setting include.lowest to true will include the lowest value. But the part about the "highest value in the second column", I don't understand what it's referring to. And what does "for right = FALSE" mean? The highest value in the second column should already be included anyway.</p>

<p>so if I have rcl=c(0,1,5, 1,Inf,10) by default it means 0>x>=1 becomes 5, and x>1 becomes 10. What happens if include.lowest is TRUE? 0>=x>=1 and....?</p>

<p>I find it confusing because the example given on the reclassify help file says that</p>

<blockquote>
  <p>all values >= 0 and &lt;= 0.25 become 1, etc. m &lt;- c(0, 0.25, 1,  0.25, 0.5, 2,  0.5, 1, 3)</p>
</blockquote>

<p>but then the reclassify function in the example doesn't use the include.lowest so it shouldn't be all values >= 0 but >0.</p>

<p>EDIT: I find the help page very confusing, and given the answer the example's explanation in the help page is wrong.</p>
