stdzStrength {EHR} | R Documentation |
This function standardizes the strength entity.
stdzStrength(str, freq)
str |
character vector of extracted strength values |
freq |
character vector of extracted frequency values |
Some strength strings may include multiple values and additional interpretation may be needed. For example ‘2-1’ likely indicates a strength of 2 followed by a strength of 1. Thus a single element may need to be standarized into two elements. This can only happen if the frequency entity is missing or in agreement (‘bid’ for example). See the ‘addl_data’ attribute of the returned vector.
