How to (and how not to) loop in R
This tutorial provides a brief introduction to using loops in R. It gives you an idea of how they work, and demonstrates that they are in fact really slow and should only be used as a last resort. Examples using lapply() and tapply() demonstrate that these are much better alternatives.
Regridding of irregular model grids
Many (most) oceanographic and climate models work on grids that are not based on standard lat-long coordinates. While it is common for these models to provide remapping and gridded outputs to make the user’s life a bit easier, it is not by any means unusual to have to do the regridding yourself. This demo shows how it can be done using the standard tools in R.
Working with Spatial Data in R
A quick overview of packages and tools in R that are useful for working with spatial, oceanographic and climate data.
