I keep getting this a
on my colour legend when I make this graph in GGPLOT2.
ggplot(sher_ei_si, aes(SI, EI, shape = crop, label = treatment, colour =
management)) +
geom_point() +
geom_text_repel(aes(SI, EI)) +
xlim(0, 100) +
ylim(0, 100) +
labs(x = "Structure", y = "Enrichment", shape = "Crop", colour =
"Management") +
geom_vline(xintercept = 50) +
geom_hline(yintercept = 50) +
scale_colour_manual(values = c("grey0", "grey60")
