PieDonut how to change color of pie and donut

ON this page, a nice solution is provided for altering colors and then removing the plotting code to allow for multipanel plotting. However, when i try this code, i get an error —
“Error in complete(df3, donut, pie) : could not find function “complete””

However,this is not an error i get with the original code function PieDonut(). So, i think the “complete” function is not the actual problem, and therefore something else is going on with the customization. Any thoughts or remedies to:

1. effectively set color scheme using something like the phrasing of —
   myColors <- brewer.pal(12, “Paired”)
   names(myColors) <- levels(data$classes)
2. Then integrate that into the base code for the setting colors as a selected color palette.
3. The freedom to plot multiple piedonuts using ggarrange or par.

I tried using the custom code and then adapting to my purpose. Then i reverted back to the code for new function in the feed. Worked with different color palette coding to customize, and then got the “complete” function error.
