How do you make a new dataset given a set of vectors?

Question

Is there a way in R to build a new dataset consisting of a given set of vectors -- median1, median2, median3, median4 -- which are median vectors from a previous dataset s?

median1 = apply(s[,c("A1","B1","C1","D1","E1","F1","G1","H1","I1")],1,median)
median2 = apply(s[,c("A2","B2","C2","D2","E2","F2","G2","H2","I2")],1,median)
median3 = apply(s[,c("A3","B3","C3","D3","E3","F3","G3","H3","I3")],1,median)
median4 = apply(s[,c("A4","B4","C4","D4","E4","F4","G4","H4","I4")],1,median)

plot(median1,median2, pch = ".")

Solution

What do you mean "build a new dataset"? Like this?

s2 <- data.frame(median1, median2, median3, median4)

Or else use cbind:

s2 <- cbind(median1, median2, median3, median4)
