Basic statistical functions for handling missing values or NA.  
In <code>log.na</code>, <code>sum.na</code>, <code>mean.na</code> and <code>var.na</code>,
<code>quantile.na</code>, <code>length.na</code>, missing values are omitted
from the calculation.  
The function <code>cor.na</code> calls <code>cor</code> with the argument
<code>use="pairwise.complete.obs"</code>.  
The function <code>order.na</code> only handles vector arguments and not
lists.  However, it gives the option of omitting the NAs
(<code>na.last=NA</code>), of placing the NAs at the start of the ordered
vector (<code>na.last=F</code>) or at the end (<code>na.last=T</code>).  
The function <code>scale.na</code> is a modified version of
<code><a rd-options="" href="/link/scale?package=marray&version=1.50.0" data-mini-rdoc="marray::scale">scale</a></code> which allows NAs in the variance calculation. If
<code>scale = T</code>, the function <code>f</code> in <code>scale.na</code> uses
<code>var.na</code> to perform the variance calculation.
The function <code>prod.na</code> is similar to the <code><a rd-options="" href="/link/prod?package=marray&version=1.50.0" data-mini-rdoc="marray::prod">prod</a></code>
function with <code>na.rm=TRUE</code>. This function returns the product of
all the values present in its arguments, omitting any missing values.
