%description
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.
