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)
我正在尝试将数据集转换为列联表,然后再转换回常规数据框:
xtabdata<-as.data.frame.matrix(xtabs(EstimatedQuantity~Date+ScowNo,
data=dataset),
row.names=(dataset$Date),optional=F)
