Freeze and thaw matrices
Description
Some terminology: * frozen variables: the variables that have fixed values * warm variables: the remaining variables that vary freely
Usage
freeze(input, frozen)
thaw(input, frozen)
Details
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.
Examples
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)
