Hi Team

Been trying to install 'RHDFS' package in R studio desktop , R cmd , and CDSW -R terminal.

Tried installing in all these environments.But still i m seeing error message saying it is not available for current R version.Tried on 3.4.4 version and 3.5.2 versions as well.

Can you please tell me how to install rhdfs package.

Thanks
Sankar

That package isn't on CRAN, it's on github:

This is where it's going wrong. You should read the documentation in the link, but the package hasn't been touched since 2013 so might not be functional anymore.

Ohh if it is not functional , do we have to another package with the similar functionality?

I don't know whether it still works or not. You should check the documentation and installation instructions before giving up on it.

There are more details here:
