saveNewComputation

The function <code>saveNewComputation</code> uses the computation definition to save
a new computation instance. This is typically done for every site that wants to participate
in a computation with its own local data. The function examines the computation definition
and uses the identifier therein to uniquely refer to the computation instance at the site.
This function is invoked (maybe remotely) on the opencpu server by
<code>uploadNewComputation()</code> when a worker site is being set up

Implementing algorithms and fitting models when sites (possibly remote) share
computation summaries rather than actual data over HTTP with a master R process (using
'opencpu', for example). A stratified Cox model and a singular value decomposition are
provided. The former makes direct use of code from the R 'survival' package. (That is,
the underlying Cox model code is derived from that in the R 'survival' package.)
Sites may provide data via several means: CSV files, Redcap API, etc. An extensible
design allows for new methods to be added in the future and includes facilities
for local prototyping and testing. Web applications are provided (via 'shiny') for
the implemented methods to help in designing and deploying the computations.

saveNewComputation function

<dl><dt>defn</dt>
<dd>an already defined computation</dd>
<dt>data</dt>
<dd>the (local) data to use</dd>
<dt>dataFileName</dt>
<dd>a file name to use for saving the data. Typically <code>NULL</code>, this
is only needed when one is using a single opencpu server to behave like multiple
sites in which case the data file name serves to distinguish the site-specific data files.
When it is <code>NULL</code>, the data file name is taken from the configuration settings</dd></dl>

possibly a data file name to use — saveNewComputation
