R-package for OPC UA

There is no native OPC UA client for R; however, you can get OPC data into your R application in a variety of ways.

• Use a commercial or write an OPC UA Client to log data into an SQL database and get it from there using R.

• Write an OPC UA Client in .NET and call it from your R application.
  • Calling .NET/C# from R
  • Is it possible call a COM object from within R, if the COM object is exposed from a .NET assembly?
  • Call R (programming language) from .net
• Write an OPC UA Client in Go and call it from your R application.

• Same can be done with Python, C, etc.

Personally, I think it would be the easiest to use a database. OPC Foundation provides a .NET Core stack where you can add your own R driver.
