Dear colleagues,
“arima” returns directly the 1-step ahead errors but I am interested in

The image function will plot a rectangle for each cell of a table with the
color of the rectangle determined by the value of the rectangle. Any cells in
the table that are NA will not produce a rectangle in the image plot.
Can you make that work for your plot?
