prop

Convert time series into proportion time series.

Tools for quickly processing and analyzing
field observation data and air quality data. This
tools contain functions that facilitate analysis
in atmospheric chemistry (especially in ozone
pollution). Some functions of time series are also
applicable to other fields. For detail please view
