I have 6 variables in my df that I want plotted in pairs (ie: 1+2, 3+4, 5+6) with 1+2 plotted together, 3+4 together, 5+6, all at the same time
using bci_js_plot <- ggplot(bci_Js, mapping = aes(TIMESTAMP, Js, color = as.factor(Port))) + geom_line() + facet_wrap(~Port, scales = "free_y")how can I code to separate/combine into the 3 graphs instead of 6
