我只想在韩国将红色设置为其他国家的黑色。 你能帮我吗?
ggplot(subset(juho, Country != 'Korea'), aes(x = YEAR, y = Mean)) +
geom_line(aes(color = Country, group = Country)) +
geom_line(data = subset(juho, Country == 'Korea'),
size = 3, linetype = 'solid', color = 'red') +
theme_bw() +
theme(legend.position = "") +
scale_x_continuous(breaks = c(2000,2003,2006,2009,2012,2015))
