Projects the (centred) columns of a matrix onto a (centered) vector and returns the slope-coefficient for each column.

projectonto(A, b)

Arguments

A	A centered matrix whose columns will be projected onto
b	this centered vector

Value

A vector of slope coefficients.

Examples

data(BCdata)
Y <- BCdata$Y
X <- BCdata$X
#Project the columns of X onto Y.
tt <- projectonto(X,Y)
