The R package PBSadmb gives complete R support to the external program AD Model Builder (ADMB) released into the public domain in 2009. The program offers users a remarkably efficient tool for estimating parameters and their uncertainty, based on complex nonlinear statistical models.
In a standard ADMB installation, users would interact with the program via a DOS command shell (in Windows) or a bash shell (in Linux or Mac OS X). The package PBSadmb makes it possible to interact entirely from an R console, as a common interface for all operating systems. A single R script can encapsulate commands to ADMB, as well as all analyses that follow. The package includes protocols for writing code to make the integration between R and ADMB almost seamless.
PBSadmb also provides a Graphical User Interface (GUI) that facilitates the steps required for a complete ADMB analysis. Both new and experienced users can use the GUI for tutorial and educational purposes.
You can obtain PBSadmb from the Comprehensive R Archive Network (CRAN). Always use the current version of PBSadmb with the most recent version of PBSmodelling, another package available from CRAN.
PBSadmb represents just one of a series of R packages developed at the Pacific Biological Station (PBS) in Nanaimo, British Columbia. A more advanced version of PBSadmb might be available at pbs-software on GitHub. Any evolving package is built after using CRAN's rigorous R CMD check --as-cran routine (on a Windows 11 64-bit system). Most of the time, the revision on GitHub can be built in R using devtools::install_github("pbs-software/pbs-admb/PBSadmb").
