[R] Concatenation

[Wu Gong]

Sorry, I made a mistake. Should add "byrow = TRUE".
Using randomly created values can't check the result, a sequence will be
better.

olddata <- data.frame(matrix(1:200, nrow=40, byrow = TRUE))
newdata <- data.frame(matrix(as.vector(t(olddata)),
nrow=nrow(olddata)/10,byrow = TRUE))
dim(olddata)
dim(newdata)
olddata[1:2,]
newdata[1:2,]
