In aba: Automated Biomarker Analysis

Description

This function creates all possible combinations of a set of variables. The variables should be given as strings and sep. This function can be used inside of a call to set_predictors when creating an aba model.

Usage

all_combos(...)

Arguments

...	strings. Variable names from which all possible combinations will be created. Each variable string should be separated by a comma.

Value

A list of vectors of all possible combinations of the variables

Examples

data <- adnimerge %>% dplyr::filter(VISCODE == 'bl')

# fit model with all combinations of three variables
model <- data %>% aba_model() %>%
  set_groups(
    everyone(),
    DX_bl %in% c('MCI', 'AD')
  ) %>%
  set_outcomes(ConvertedToAlzheimers, CSF_ABETA_STATUS_bl) %>%
  set_predictors(
    all_combos('PLASMA_ABETA_bl', 'PLASMA_PTAU181_bl', 'PLASMA_NFL_bl')
  ) %>%
  set_stats(
    stat_glm(std.beta = TRUE)
  ) %>%
  fit()

model_summary <- model %>% aba_summary()
