如果一個(gè)三維的數(shù)據(jù)導(dǎo)出csv文件后，再從csv導(dǎo)出時(shí)如何導(dǎo)出成三維的數(shù)據(jù)？
#?Create?two?vectors?of?different?lengths.
>?vector1?<-?c(5,9,3)
>?vector2?<-?c(10,11,12,13,14,15)
>?column.names?<-?c("COL1","COL2","COL3")
>?row.names?<-?c("ROW1","ROW2","ROW3")
>?matrix.names?<-?c("Matrix1","Matrix2")

怎么導(dǎo)出成老的數(shù)據(jù)？
