Reformat biomarker_map or model_pars exposure and biomarker variables

Source: R/misc_functions.R

This function will reformat the biomarker_map or model_pars objects so that exposure_ID and biomarker_ID are either both numeric (if passed as characters) or characters (if passed as numeric).

reformat_biomarker_map(input_map, exposure_key = NULL, biomarker_key = NULL)

Arguments

input_map

A tibble specifying the relationship between exposure IDs and biomarker IDs

exposure_key

Optional vector giving the character-index relationship for exposure_id

biomarker_key

Optional vector giving the character-index relationship for biomarker_id

Value

input_map is returned with unique numeric or character inputs for exposure and biomarker IDs

Examples

## Convert characters to numeric
biomarker_map <- dplyr::tibble(exposure_id=c("infection","vaccination"),biomarker_id=c("IgG","IgG"))
reformat_biomarker_map(biomarker_map)
#> # A tibble: 2 × 2
#>   exposure_id biomarker_id
#>         <dbl>        <dbl>
#> 1           1            1
#> 2           2            1

## Convert numeric to characters
biomarker_map <- dplyr::tibble(exposure_id=c(1,2),biomarker_id=c(1,1))
reformat_biomarker_map(biomarker_map, exposure_key=c("infection","vaccination"),biomarker_key=c(1))
#> # A tibble: 2 × 2
#>   exposure_id biomarker_id
#>   <chr>              <dbl>
#> 1 infection              1
#> 2 vaccination            1
