[R] need help for predictive analytics part

[Swapnil Khobragade]

Hello sir,

 Actually, I 'm novice to R programming and currently working on prediction part for CPU usage log file (attached with mail).
My task is to predict next hour CPU usage by taking "Time" as response and  %user    %nice   %system   %iowait    %steal     %idle, either all or one as predictor(s).
Please help me out.

I have attached CPU usage log file with mail.
Please find attachment.


Thank You in advance.
