Introduction
This document describes the use of the functions implemented in DescriptiveStats.OBeu package in OpenCPU environment, after installing OpenCPU and DescriptiveStats.OBeu package on OpenCPU server address(/ocpu/test).
How to use functions

ds.analysis
In this example we will use ds.analysis
function that returns in a single call a json string or a list with the following components:

Select library and function
Go to: yourserver/ocpu/test
Copy and paste the following function to the endpoint
../library/DescriptiveStats.OBeu/R/ds.analysis
# library/ {name of the library} /R/ {function}
