Examples

# The HLA_typing_LIS dataset contains a table as might be found in a clinical
# laboratory information system:
print(HLA_typing_LIS)

# The `HLA_prefix_add` function can be used to add the correct HLA prefixes to the table:
library(dplyr)
HLA_typing_LIS %>% mutate(
  across(
    mA1Cd.recipient:mA2Cd.recipient,
    ~ HLA_prefix_add(., "HLA-A*")
  )
)
