Hello,  
While installing ITKR with devtools I have this error:

What is ITKR? We [dropped wrapping](https://github.com/InsightSoftwareConsortium/ITK/pull/3212) for all languages except Python quite a while ago.

I believe its @stnava 's wrappings: [GitHub - stnava/ITKR: port of ITK to R](https://github.com/stnava/ITKR) @ntustison May be a contributor or maintainer too.

Also we (ITK community) do have support for other languages such as with SimpleITK’s R support and other languages. 🙂
