Extract the captured console trace from an hzr_stepwise fit

Source: R/stepwise.R
stepwise_trace.Rd

Every run of hzr_stepwise() records the header, per-step lines, and final summary regardless of the trace flag. This accessor returns the full character vector for display or logging.

Usage

stepwise_trace(fit)

Arguments

fit

An hzr_stepwise object.

Value

Character vector, one element per console line.

See also

hzr_stepwise(), which produces the object this accessor reads.

Examples

data(avc)
avc <- na.omit(avc)
base <- hazard(survival::Surv(int_dead, dead) ~ age,
               data = avc, dist = "weibull", fit = TRUE)
# \donttest{
sw <- hzr_stepwise(base, scope = ~ age + nyha,
                   data = avc, direction = "forward",
                   control = list(n_starts = 1))
#> Stepwise selection (direction = forward, criterion = wald, slentry = 0.30, slstay = 0.20)
#> 
#> Warning: Stepwise forward: candidate refit failed for nyha.
#> (no further action after 0 steps)
#> 
#> Final model: 0 covariates, logLik = NA, AIC = NA
cat(stepwise_trace(sw), sep = "\n")
