dimfig
chooses the set of units that provides the most concise representation for data
, and sigfig
concisely represents statistical estimates with a fixed number of significant digits.
dimfig
returns a list
with slots for the converted data
and the name of the most concise units. sigfig
returns a character string that is formated with the specified number of significant digits.
