Re: [R] ggplot2::geom_path() in a loop problems.

Sigh. Don't do this. Setup your data frame with all the data you want to plot and give it to one geom. Use group columns such as factors (e.g. color, size, linetype, etc) to distinguish them. Using multiple geoms with different mappings is usually a recipe for disappointment. It also fails to c
