saveNewNCP

The function <code>saveNewNCP</code> uses the list of sites
definition to save a new NCP instance. This is
typically done for every pair of NCPs used in a computation. 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.

saveNewNCP function

<dl><dt>defn</dt>
<dd>a definition of the ncp</dd>
<dt>comp_defn</dt>
<dd>the computation definition</dd>
<dt>data</dt>
<dd>the list of sites with name and url 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 definition settings</dd></dl>

possibly a data file name to use — saveNewNCP
