如何使用R合并具有不同大小的向量

Question

I am trying to put together 3 vectors of different sizes in R but i keep getting error message

First i created a dummy vector

dummy <- mat.or.vec(10,3)
dummy[,1] <- myVec1
dummy[,2] <- myVec2
dummy[,3] <- myVec3

Since all myVec1, myVec2 and MyVec3 has different sizes i get the following error message

number of items to replace is not a multiple of replacement length

Answer 1

I dont really understand why you are combining three columns of different lengths. But maybe this will get you the results you're after

dummy <- mat.or.vec(10,3)
dummy[1:length(myVec1), 1] <- myVec1
dummy[1:length(myVec2), 2] <- myVec2
dummy[1:length(myVec3), 3] <- myVec3
