I use the forecasting package and I want to plot the acf of a time series. Strangely the acf is only calculated until a certain lag (about 35) and afterwards is not displayed anymore altough there is in fact autorcorrelation also for larger lags. Here you can see the data and the acf plot in a screenshot
Here you see the R code:
L <- acf(generationData$Price, plot = FALSE)
plot(L, xaxt = 'no', xlim = c(1,50))
axis(1, at = c(1,5,10,50,75,125), xlim = c(1,200))
Can you tell me what the problem is? This also happens when using other time series data. The acf is not plotted for larger lags. I'd appreciate every comment.
