[R] to change the size of the line in the plot created in ggplot2
Hi R user, I was trying to make a figure for each of four sites. Each site has 7 classes, among the 7 classes, one is average. I am wondering how I can change the color and size of the line that was average value. I want to highlight average value. Similarly, I have been using smooth function therefore I want to highlight the smoothed line but still I want to show a original data with gray colour. I tried it different ways but I could not change the line style (or size) and colour. would you please give me a suggestion on how I can solve the problem? I used the following code.> unique(dat$site)[1] SiteA SiteC SiteB SiteD Levels: SiteA SiteB SiteC SiteD> unique(dat$variable)[1] D C E Average F A B Levels: A Average B C D E F A<-ggplot(data=dat, aes(x=Year, y=value, group = variable, colour variable)) +geom_line()+theme_bw()+stat_smooth() A+facet_wrap(~ site, ncol=2)Thanks [[alternative HTML version deleted]]
