R语言，安装完成ggplot2后运行报错：”> library(ggplot2)Warning message:
程辑包‘ggplot2’是用R版本3.1.3 来建造的 “


请问怎么解?

网上有说用3.13之前的版本，可官网上已经将旧版本的R取消下载了

急求解答，谢谢！[em23][em23]

执行这个语句：
library(ggplot2)
OR<-c(.508, .734, .418, .674, .610, .694, .567, .214)
lower<-c(.340, .587, .275, .363, .475, .386, .348, .031)
upper<-c(.759, .919, .636, 1.252, .784, 1.248, .925, 1.478)
type<-c(1,1)
odds<-data.frame(OR, lower, upper,type)
vars<-c("Hypertension(+)","Hypertension(-)","obesity(+)","obesity(-)", "Dyslipidemia(+)","Dyslipidemia(-)","central obesity(+)","central obesity(-)")
ticks<-c(seq(.1, 1, by =.1), seq(0, 10, by =1), seq(10, 100, by =10))
a1<-ggplot(odds, aes(y= OR, x = vars)) +scale_y_log10()
a3<-a2+geom_errorbar(aes(ymin=lower, ymax=upper), width=.1,lwd=1)
a4<-a3+geom_hline(yintercept = 1, linetype=2)
a5<-a4+coord_flip()+ facet_wrap(~type,nrow=2)
a6<-a5+labs(title = "", x = "", y = "Odds ratio for DM")
a7<-a6+theme_bw()

提示:    Error: object 'a2' not found

你没定义a2啊

目前最新的R正式版就是3.1.3。这个错误的原因确实是没有定义a2.
