This is a simple wrapper function to define special smooth terms
in BAMLSS formulae. The function calls the smooth term constructor function
s. The return value of
s is only slightly
modified, such that function
bamlss.frame identifies this term as a special
term and uses the appropriate (internal) infrastructures.
This structure is useful when the model term structure is, e.g., not a
linear combination of a design matrix and coefficients. See the example section of
bfit on how to use this setup.
