运行代码后出现报错，Error in FUN(X[[i]], ...) : object 'Pathway' not found，如何解决？

R语言小白，百度搜了一段KEGG气泡图的代码，修改文件运行后仍出现报错，如何解决？谢谢各位大佬！

```> setwd("F:/Research/gse27447/DAVID")
> library(ggplot2)
> pathway = read.csv("KEGG2.csv",header=TRUE,row.names=1,check.names = FALSE)  
> p = ggplot(pathway,aes(Pvalue,Pathway))
> p=p + geom_point()  
> # 修稿点的大小
> p=p + geom_point(aes(size=Count))
> # 展示三维数据
> pbubble = p+ geom_point(aes(size=Count,color=-1*log10(Pvalue)))
> # 设置渐变色
> pr = pbubble+scale_color_gradient(low="green",high = "red")
> # 绘制p气泡图
> pr = pr+labs(color=expression(-log[10](Pvalue)),size="Count",  
+              x="Pvalue",y="Pathway name",title="Pathway enrichment")
> pr + theme_bw()
Error in FUN(X[[i]], ...) : object 'Pathway' not found
> ## 保存图片
> ggsave("out.pdf")# 保存为pdf格式
Saving 7.64 x 5.6 in image
Error in FUN(X[[i]], ...) : object 'Pathway' not found
> ggsave("out2.png",width=4,height=4)# 设定画布大小
Error in FUN(X[[i]], ...) : object 'Pathway' not found

p = ggplot(pathway,aes(Pvalue,Pathway))

最后的Pathway 是不是应该是前面的小写的pathway？
改一下试试
