Software Version: 0.1.0

Babies born small for gestational age (SGA) or large for gestational age (LGA) have a higher risk of morbidity and mortality. Small is often defined as <= 10th percentile given the baby's sex and gestational age, or <= 3rd percentile given the baby's sex and gestational age. Similarly, LGA is often defined in terms of the 90th.

Finding look-up tables is straightforward enough, but these are not particularly useful for processing millions of records. This trivial package gives a percentile classifications (weight for gestational age and sex) for a single infant (ga_class()) or a dataframe of millions of infants (ga_dataframe()).

The possible percentile classes are: "<= 03", "<= 05", "<= 10", "10-90", ">= 90", ">= 95", ">= 97"

When processing a dataframe, the entire dataframe is returned with an additional column (ga_class)
