[R] R 3.3.0 Crashing: Error in readRDS(nsInfoFilePath) : unknown input format

[Amitava Mukherjee]

Dear All,

Greetings. I hope you will be able to provide kind help with the following:

I am facing a strange problem ever since I have started working with R
3.3.0.

I download and work with it, it was fine. Then when I shut down and reopen,
it is not working properly.

I am getting following message:

Error in readRDS(nsInfoFilePath) : unknown input format

I have uninstall it three times and reinstall -- Every time after first
installation it is working perfectly.

Then when I am closing R window and reopening it, the problem starts.

Kindly suggest what should I do. Looking forward to hear from you,

Best regards,
Amitava
