Ecosystem Modelling Practicals
Dear Students,
You will find here attached:
1) list of exercices that we will do during the practicals
2) R script for the first exercise (you will do the other scripts yourselves and I will give you the corrected version afterwards)
3) A Pdf describing the code in an easier way.
You will need :
Rmarkdown, deSolve, marelac, FME, diagram.
Next lecture: Tuesday November 19th, 2PM, B22/1, Auditoire 0/35.
Have a great week-end,
Marilaure Grégoire
