Dear All, I am struggling with extracting data from a data frame: x=data.frame(a=1:11,b=100:110)
What I want is a list/vector in this sence: 1 100 2 101 3 102... For single rows, this works fine: as.matrix(x)[1,] For, say 2 rows, this works fine: z=c(as.matrix(x)[1,],as.matrix(x)[2,]) But z=c(as.matrix(x)[1:2,]) gives 1 2 100 101!? Is there an 'automated way' to produce a list/vector from a data frame in which data of each row are just added to the end of the previous row?
