I am fitting a time series model in R. I plotted the time series to check for the pattern of it. It has 30625 observations. The observations are half hourly
I took the logarithm of the series and then checked its acf plot.
I am getting an error
Error in plot.window(...) : need finite 'ylim' values In addition: Warning messages: 1: In min(x) : no non-missing arguments to min; returning Inf 2: In max(x) : no non-missing arguments to max; returning -Inf
What does this error means? What should I do remove this error. I also think the significance bounds given by dotted line are not correctly calculated. What should I do in these two cases?
