Openanalytics/r-base for arm64 architecture

Hi:

I’m trying to run a Shinyproxy app (R Shiny dockerized) on an EC2 instance on arm64 architecture, after multiples issues I found out that I need and arm64 based image, checking on GitHub I see that:

openanalytics/r-base

Is linux/arm64 based. Is there an alternative to this image (Ubuntu 20.04 LTS with R ) but for the arm64 architecture?

Thanks!
