Wouter's R code pages
TOPMODEL
This page contains some functions and code snippets for hydrological data analysis with R, that may eventually make it into a properly released R package. For now, the code can be downloaded on this page and used at your own risk, without official support (although I very much welcome all feedback). The core of the package is an implementation of the venerable TOPMODEL.
Information on R, including downloads, installation and a great choice of manuals can be found on the R website. If you follow strictly the examples used below, you will be able to run TOPMODEL with a very limited R knowledge. However, R has a great potential for pre- en postprocessing of the data (including uncertainty analysis and statistics), so a more extensive knowledge of R is highly recommended!
Thanks go to Keith Beven, who wrote the original TOPMODEL in Fortran, and Huidae Cho, for the C code base (originally implemented in GRASS GIS)
The following examples are currently available:
- various functions, including data processing and topographic index calculation
- TOPMODEL
- GLUE uncertainty analysis
Downloads
Installation
Windows
Local packages can be installed from the menu. Choose "install package(s) from local zip files" and select the downloaded topmodel_0.3.zip file.
Linux
Use the normal procedure of installing a package in R (you may have to be root):
R CMD install topmodel_0.3.tar.gz
Developer tools, including gcc, must be installed.Mac
Go to the Package Installer (Packages and Data menu), select "Local Binary Package", click install and select the downloaded package
Loading
Once in R you need to load the package before you can use it:
library(topmodel)
