我从以下内容开始生成第一条回归线和散点图：

lm<-ggplot(onepctCO2MEDIAN) +  
geom_jitter(aes(RCP1pctCO2cumulativeMedian[1:138], departurea),   
colour="blue") + geom_smooth(aes(RCP1pctCO2cumulativeMedian[1:138], 
departurea), method=lm)

但是我收到此错误：

Warning message:
Computation failed in `stat_smooth()`:
'what' must be a function or character string

成功创建了蓝色散点图，但问题在于没有出现回归线，可能与上述警告有关。

这是有原因的吗？我将不胜感激！

通过执行以下操作，您应该能够获得带有回归线的散点图：
