R语言中xcms中运行出现的问题

丧猫

分组不知道是不是太多了，有12个分组，在reporttab <- diffreport(xset3,"GroupA","GroupB","GroupC","GroupD","GroupE","GroupF","GroupG","GroupH","GroupK","GroupL","abc"）,10,metlin = 0.15,h=480,w=640)，write.csv(reporttab,file="D:/faahko2.csv")这条命令运行不出结果，提示错误为Error in is.data.frame(x) : object 'reporttab' not found，求大神解答~~
