使用as.data.frame.matrix时保留行名称

r dataframe

使用as.data.frame.matrix时保留行名称,r,dataframe,R,Dataframe,我有以下数据集： Date<-c("9/7/2010","9/7/2010","9/7/2010", "9/7/2010","9/7/2010","9/7/2010","9/8/2010") EstimatedQuantity<-c(3535,2772,3279,3411,3484,3274,3305) ScowNo<-c("4001","3002","4002","BR 8","4002","BR 8","4001") dataset<- data.f

我有以下数据集：

Date<-c("9/7/2010","9/7/2010","9/7/2010",
        "9/7/2010","9/7/2010","9/7/2010","9/8/2010")
EstimatedQuantity<-c(3535,2772,3279,3411,3484,3274,3305)
ScowNo<-c("4001","3002","4002","BR 8","4002","BR 8","4001")

dataset<- data.frame(EstimatedQuantity,Date,ScowNo)

Date这就是你想要的吗
as.data.frame(unclass(xtabs(EstimatedQuantity~Date+ScowNo,data=dataset)))

unclass是杀手！
as.data.frame(unclass(xtabs(EstimatedQuantity~Date+ScowNo,data=dataset)))
