Does anyone know how this can be done?
Heres my code:
FuncGrpPlot <- ggplot(SummFuncGrpMAIZEna, aes(FuncGrp, yi))+
geom_col(fill="lightgrey", colour="black") +
geom_errorbar(aes(ymin = yi - ci, ymax = yi + ci), width=0.3) +
ggtitle("Effect of Bt Maize on Abundance of Arthropods, by Function Group") +
labs(y="Effect Size", x = "Function Group") + theme_bw()
Can't paste chart in unfortunately but it's a bar chart with error bars on. Just want sample sizes to appear next to the top or bottom of each bar. Sample sizes are contained in my 'SummFuncGrpMAIZEna' summary table.
