surv_model_info function

Extract additional information from the model

This generic function let user extract base information about model. The function returns a named list of class model_info that contain information about package of model, version and task type. For wrappers like mlr or parsnip both, package and wrapper information are stored

Details

Currently supported packages are:

• class coxph - Cox proportional hazards regression model created with survival package
• class model_fit - models created with parsnip package
• class ranger - random survival forest models created with ranger package
• class rfsrc - random forest models created with randomForestSRC package

Examples

library(survival)
library(survex)
cph <- survival::coxph(survival::Surv(time, status) ~ .,
    data = veteran,
    model = TRUE, x = TRUE, y = TRUE
)
surv_model_info(cph)

library(ranger)
rsf_ranger <- ranger::ranger(survival::Surv(time, status) ~ .,
    data = veteran,
    num.trees = 50, mtry = 3, max.depth = 5
)
surv_model_info(rsf_ranger)
