Click for ACF image 2
These are my ACF and PACF of my data set . Can any one help me determine whether the data is stationary ? if so What order of AR , MA ?
The periodicity in your (P)ACF plots strongly suggests seasonality of length slightly less than 0.02 of the cycle you defined. Since $7/365\approx 0.019$, I suspect that you have daily data, which you specified as
frequency=365. We can't say much more.
Note that it is not very good practice to examine (P)ACF plots any more (the box-jenkins approach). Nowadays, it's better to choose models based on AIC, after determining any necessary differencing using appropriate methods. I suggest you look at
?forecast::auto.arima and FPP2.
If you do have daily data with possible intra-yearly seasonality, you may want to look at our multiple-seasonalities tag.
