update.blrmfit: Update data of a BLRM analysis

In OncoBayes2: Bayesian Logistic Regression for Oncology Dose-Escalation Trials

Update data of a BLRM analysis

Description

Adds data rows to a blrm_exnex or blrm_trial analysis object.

Usage

## S3 method for class 'blrmfit'
update(object, ..., add_data)

Arguments

object	blrmfit analysis object
...	passed to default update command The data in add_data will be combined with data in object using bind_rows. The indices for groups and stratums (if defined) are matched between add_data and the data of the analysis object. Note that the add_data argument must be named explicitly as demonstrated in the example.
add_data	additional data added to analysis data of object

Examples

## Setting up dummy sampling for fast execution of example
## Please use 4 chains and 100x more warmup & iter in practice
.user_mc_options <- options(
  OncoBayes2.MC.warmup = 10, OncoBayes2.MC.iter = 20, OncoBayes2.MC.chains = 1,
  OncoBayes2.MC.save_warmup = FALSE
)

example_model("single_agent", silent = TRUE)

library(tibble)
new_cohort <- tibble(group_id = "trial_A", drug_A = 50, num_patients = 4, num_toxicities = 1)

## this would fail, since add_data argument must be named
## new_blrmfit <- update(blrmfit, new_cohort)
new_blrmfit <- update(blrmfit, add_data = new_cohort)

## Recover user set sampling defaults
options(.user_mc_options)
