I recently had a user encounter this error when running an rsyncrosim script to load a library using ssimLibrary() for the first time on a new computer:
Error in .local(.Object, …) :
No base packages are installed. Use addPackage() or addPackageFile() to install a package.
 “Error in .local(.Object, …) : \n No base packages are installed. Use addPackage() or addPackageFile() to install a package.\n”
You can either install the base package you need by calling rsyncrosim::addPackage(“package name”) or opening SyncroSim in the GUI and selecting “File | Packages” and then “Install…” and selecting the package that you want. You can also install a package from file by calling rsyncrosim::addPackageFile(“file path”) or in the GUI selecting “File | Packages” then “Install from File…”.
