我目前正面临使用ggplot2的错误.我想使用此数据框创建一个标准错误栏的条形图:
mean se pattern quality
1 54.955357 19.792315 spread good
2 54.506944 18.580981 clumped good
3 29.604167 14.937291 centered good good
5 23.300595 14.336305 spread bad
6 8.371528 5.960366 clumped bad
7 16.364583 11.525207 centered good bad
8 7.062500 11.125915 centered bad bad
我使用这个公式来创建我的条形图:
ggplot(table, aes(x=pattern, y=mean, fill=quality))+
geom_bar(position="dodge")+
geom_errorbar(aes(ymin=mean-se, ymax=mean+se,
width=0.2, position=position_dodge(0.9)))
但是当我运行它时,应该有我的条形图的窗口显示为空白,并弹出此错误消息
