为第33至48行创建了并排条形图：

library(ggplot2) #development version

p<-ggplot(df2[33:48,], aes(x=Year, y=value, fill=pos)) + 
   geom_bar(stat='identity', position='identity') + ggtitle("OMO (Rs'crores)\n") + theme(plot.title = element_text(lineheight=.8, face="bold",colour = "darkred",hjust =0.5,vjust = 2,size = 9)) + labs(x = "\nYear", y = "Rs crores\n",caption="Sources:Data is from RBI site")+scale_y_continuous(limits = c(-65000,200000),breaks =c(-60000,-30000,0,30000,60000,90000,120000,150000,180000,180000)) + scale_x_date(date_breaks = "2 year",date_labels = "%Y") 
p

我想在上面的条形图上添加（覆盖）行1到16和17到32作为2个单独的线图：

我试过了：

添加第一行（变量==“购买”）     p + geom_line（df2 [1:16]，aes（x =年，y =值））     错误：ggplot2不知道如何处理class uneval的数据

我哪里错了？

我认为这是关于你想要的。我重新排列了数据帧，并稍微调整了一下值，并为这些行添加了一个图例。 

library(ggplot2)
df2 <- read.table(stringsAsFactors=F,text=
"Year variable     value   pos
1  2001-04-01 Purchase   4471.05  TRUE

重写上述解决方案以使其正确

重新排列数据框

df2$Year <- as.Date(df2$Year)
df3 <- df2[33:48,]
df3$purchase <- df2[1:16,"value"]
df3$sales<- df2[17:32,"value"]
df3

没有情节

p<-ggplot(df3, aes(x=Year, y=value)) +

酒吧

geom_bar(aes(fill=pos),stat='identity', position='identity') + scale_fill_manual(name="Positive",values=c("TRUE"="#00BFC4","FALSE"="#F8766D")) + theme(panel.grid.minor = element_line(colour = "black", linetype = "dotted",size = 0.3)) + theme(panel.grid.major = element_line(colour = "black", linetype = "dotted",size = 0.3)) + theme(plot.background = element_rect(fill="#e0edbd" )) + theme(panel.background = element_rect(fill = "#fbfefe")) + scale_fill_discrete(name="",breaks=c("TRUE","FALSE"),labels=c("Net Purchases(+)","Net Sales(-)")) +

线条

    geom_line(aes(x=Year,y=purchase,color="purchase"),size=1.35) +   geom_line(aes(x=Year,y=sales,color="sales"),size=1.35) + scale_y_continuous(limits = c(-65000,200000), breaks = 30000*(-2:6)) + 
  scale_x_date(date_breaks = "2 year",date_labels = "%Y") + scale_colour_manual(name="",values=c("#0072B2","#D55E00"),breaks=c("purchase","sales")) + ggtitle("Open Market Operation(OMO) since 2001 (Rs'crores)\n") + 
  theme(plot.title = element_text(lineheight=.8, face="bold",colour = "darkred",hjust =0.5,vjust = 2,size = 9)) + labs(x = "\nYear", y = "Rs'crores\n",caption="Sources:Data is from RBI site") + theme(plot.caption=element_text(size=8, hjust=1.4, margin=margin(t=10)))
