[R] load() failed to load .Rdata file in AWS-Ububtu

[Christofer Bogaso]

Hi again,

I hope this is the right place to post my question on running R within
Ubuntu, however if not, any pointer on right distribution list will be
helpful.

I am currently using R in Ubuntu which is hosted in Amazon - AWS.

I have a .Rdata file in AWS which I am trying to load in R. Used
following code, however, fails to load showing some permission issue.
However that same .Rdata file is getting loaded perfectly when I try
in my regular iOS.

Below is my code and corresponding result :

ubuntu at ip-172-31-23-148:~$ R


R version 3.4.2 (2017-09-28) -- "Short Summer"

In addition: Warning message:

Can someone help me to understand where it went wrong with Ubuntu? I
also tried with changing the extension from .Rdata to .RData, however
observing the same error.

Any pointer will be highly appreciated.

Thanks for your time.
