How do I alter colour of bars in ggplot? I just want to make them a light grey so the error bars show up.
Here is my code:
FuncGrpPlot <- ggplot(SummFuncGrp1, aes(FuncGrp, yi)) +
geom_errorbar(aes(ymin = yi - ci, ymax = yi + ci), width=0.2)
FuncGrpPlot + labs(y="Effect Size", x = "Function Group") + theme_bw()
