我有一组系数估计值,以及来自R包BMA
的标准误差。我想生成一个显示其值的数字,带有误差条。我已经能够制作情节,但无法改变传说。
我的代码是:
ggplot(res.BMA[-c(1,8),], aes(x = Beta, y = EV)) +
geom_errorbar(aes(ymin = EV-SD, ymax = EV+SD), width = 0.1) +
geom_point(aes(size = Psize)) +
facet_wrap(~Year) +
xlab("Parameter") +
ylab("Estimated Value") +
scale_fill_discrete(name = "P!=0", labels = c("0-20", "20-40", "40-60", "60-80", ">80"))
我希望传说中的标题是" P!= 0"而不是Psize(任何关于改变的指导!=不等于[\u2260]
也将被赞赏),并且标签是" 0-20"," 20-40&#34 ;," 40-60"," 60-80"," 80-100"而不是1,2,3,4,5。
最终,这将基于theme_bw
在自定义主题中绘制,以清理轴等。任何指导都将不胜感激!

答案 0 :(得分:3)
您只是使用了错误的属性。
n <- 14
set.seed(1234)
df <- data.frame(Year=sample(c("1978","2001"),n,replace=T),Beta<-1:n,
Psize=sample(1:5,n,replace=T),EV=rnorm(n,2),SD=rnorm(n,0.1,0.1))
ggplot(df, aes(x = Beta, y = EV)) +
geom_errorbar(aes(ymin = EV-SD, ymax = EV+SD), width = 0.1) +
geom_point(aes(size = Psize)) +
facet_wrap(~Year) +
xlab("Parameter") +
ylab("Estimated Value") +
scale_size_continuous(name = "P!=0",
