GUI Tools Made Easy: Interact with Models, Explore Data, Give Dynamic Presentations CRAN Task View: Spatial (http://CRAN.R-project.org/view=Spatial) PBS Modelling 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 it depends heavily on the R interface to the Tcl/Tk package, a user does not need to know Tcl/Tk. The package contains examples that illustrate models built with other R packages, including PBSmapping, deSolve, PBSddesolve, and BRugs. It also serves as a convenient prototype for building new R packages, along with instructions and batch files to facilitate that process. The R directory '.../library/PBSmodelling/doc' includes a complete user guide PBSmodelling-UG.pdf. To use this package effectively, please consult the guide. Software Depends: R (>= 2.7.0), methods Suggests: PBSmapping, PBSddesolve, deSolve, KernSmooth, XML Jon Schnute <Jon.Schnute@dfo-mpo.gc.ca> Jon T.
