Hi all,

I tended to use rbind, or cbind to force a vector be be deemed as a column or row vector. This is very important if I want to do things like u' * A * u, where u' is a row vector and u is a column vector, regardless of what originall format the "u" is... I want to recast it to column vector or row vector... How can I do that?

b_hat=solve(t(X) %*% X) %*% t(X) %*% Y;

attr(b_hat, "dim")

[1] 4 1

rbind(b_hat)

[,1]
