flatten: Convert a structured coefficient set to a vector

In sgaure/durmod: Mixed Proportional Hazard Competing Risk Model

Description

mphcrm stores coefficients in a list, not in a vector. This is because they should be treated differently according to whether they are probabilities, proportional hazards, or coefficients for factor levels or ordinary covariates. flatten extracts them as a named vector. unflatten puts them back in structured form.

Usage

flatten(x, exclude = attr(x, "exclude"))

unflatten(
  flesh,
  skeleton = attr(flesh, "skeleton"),
  exclude = attr(flesh, "exclude")
)

Arguments

x	parameter set as typically found in opt[[1]]\$par, where opt is returned from mphcrm.
exclude	For internal use
flesh	vector of class "relistable", as returned from flatten.
skeleton	For internal use

Details

flatten/unflatten is just a thinly disguised unlist/relist, but uses slightly more readable names.
