GUI Tools Made Easy: Interact with Models and Explore Data R package PBSmodelling version 2.70.2 CRAN Task View: DifferentialEquations (https://CRAN.R-project.org/view=DifferentialEquations) CRAN Task View: Spatial (https://CRAN.R-project.org/view=Spatial) Provides software to facilitate the design, testing, and operation of computer models. It focuses particularly on tools that make it easy to construct and edit a customized graphical user interface ('GUI'). Although our simplified 'GUI' language depends heavily on the R interface to the 'Tcl/Tk' package, a user does not need to know 'Tcl/Tk'. Examples illustrate models built with other R packages, including 'PBSmapping', 'PBSddesolve', and 'BRugs'. A complete user's guide 'PBSmodelling-UG.pdf' shows how to use this package effectively.
