In this video barplot with error-bar has been plotted without calculating summary statistics before the ggplot function.
Instead of stat = Identity, stat="summary" has been used to determine the length of the bar as the mean of the values, and error bars are plotted using the stat_summary layer.
code of the plot is as follows:
library(ggplot2)
head(ToothGrowth)
summary(ToothGrowth)
ToothGrowth$dose
ggplot(ToothGrowth,aes(supp,len,fill=as.factor(dose)))+
geom_bar(stat="summary",fun="mean",position="dodge")+
stat_summary(geom="errorbar",fun.data = mean_se,
position=position_dodge(width=0.9),width=0.5)+
theme_classic()+
theme(legend.position = "top")+
labs(x="Suppliment",y="Length of tooth",fill="dose")
