Hi @rnsarma,
Are you planning to use these versions of R with an RStudio product?
RStudio Server Pro and RStudio Connect both work well with multiple versions of R. Our open source products are designed to be used with only one version of R at a time.
Here is our suggested R install path: https://docs.rstudio.com/resources/install-r/
Please feel free to respond with any further questions!
