R Scripts used at PEARL
The 'jezioro' package for R (by Adam Jeziodski)
The 'jezioro' (polish for 'lake') R package is a collection of functions and datasets intended to simplify some of the work performed at PEARL.
The current version (0.20) contains ten functions that can help perform some of the common analyses done in our lab. Including things like:
- determining the number of individuals represented in counts of cladoceran remains
- inferring VWHO from sedimentary chironomid assemblages
- inferring sedimentary chlorophyll a from spectral measurements of sediment intervals.
The package also contains master copies of some commonly used datasets.
