Sorry, forgot to link the actual vignette:

In fact the vignette states:
dwplot(m1_df) #same as dwplot(m1)

where m1_df is m1_df <- tidy(m1)

They are not the same in either the vignette itself or on my computer.

I don't understand the part about "rescale the coefficients", but it seems
that that is now the default... Just visually at least...

If the plots in the vignette are auto-generated from code, then that would
explain why the discrepancy isn't mentioned in the text.
