Resolving Overplotting Errors in ggplot: Tips for Choosing the Right Smoothing Method
You are getting this error because the grouping instruction is applied within the ggplot() function, but you need to apply it within the geom_line(). This will prevent overplotting of lines for each unique value in anon_screen_name. The error message also suggests that the span is too small, which means the smoothing trendline is trying to fit a curve through the data points with too few degrees of freedom. To solve this issue, you can increase the span of the smoothing trendline by adding the following code:
