Freeze and thaw matrices
1 | freeze(input, frozen)
|
Some terminology: * frozen variables: the variables that have fixed values * warm variables: the remaining variables that vary freely
A frozen matrix specifies which variables to fix in a projection
matrix. Warm variables should be missing (NA
) while frozen
variables should be set to their fixed values.
1 2 3 4 5 6 7 | frozen <- matrix(NA, nrow = 4, ncol = 2)
frozen[3, ] <- .5
input <- basis_random(4, 2)
freeze(input, frozen)
thaw(input, frozen)
freeze(basis_random(4, 2), frozen)
