small_count_label

This function labels values in a vector as a replacement string if they are
smaller than a specified cutoff. The input can be numeric, and the function
will return either a modified version of the input vector with small values
replaced by a given label, or it will keep the original values otherwise.

Hospitals, hospital systems, and even trauma systems that provide care to injured patients
may not be aware of robust metrics that can help gauge the efficacy of their programs in saving the lives
of injured patients. 'traumar' provides robust functions driven by the academic literature to
automate the calculation of relevant metrics to individuals desiring to measure the performance of their
trauma center or even a trauma system. 'traumar' also provides some helper functions for the data analysis
journey. Users can refer to the following publications for descriptions of the methods used in 'traumar'.
