When you plot a fit object, it automatically adds a legend. For example, 'plot(myfit)', in which 'myfit' is the output of 'fit' would plot the fit line and a legend showing that line with the name "fitted". If you're plotting fit objects in a loop, the legend really slows it down, and, also, I don't want the legend. I tried removing the legends after the plot is done plotting, but the slow part is making the legends, so that doesn't help. Not sure if it's relevant, but this is in a plot with 42 subplots. I did some searching, but couldn't find this particular question asked before. Anyway to just not make the legend to begin with?
