Try these: search() sessionInfo() loadedNamespaces() The first two show the attached packages (and some other info) and the last one shows the namespaces that are loaded. Note that detaching a package does not unload its namespace and unloading a namespace does not de-register its methods. This illustrates the behavior:> search()[1] ".GlobalEnv" "package:stats" "package:graphics" [4] "package:grDevices" "package:utils" "package:datasets" [7] "package:methods" "Autoloads" "package:base"> loadedNamespaces()[1] "base" "graphics" "grDevices" "methods" "stats" "utils"> as.Date(1) # error as there is no numeric method for as.DateError in as.Date.default(1) : do not know how to convert '1' to class "Date"> library(zoo) > search()[1] ".GlobalEnv" "package:zoo" "package:stats" [4] "package:graphics" "package:grDevices" "package:utils" [7] "package:datasets" "package:methods" "Autoloads" [10] "package:base"> loadedNamespaces()[1] "base" "graphics" "grDevices" "grid" "lattice" "methods" [7] "stats" "utils" "zoo"> as.Date(1) # zoo defines a numeric method for as.Date[1] "1970-01-02"> detach() > unloadNamespace("zoo")<environment: namespace:zoo>> search()[1] ".GlobalEnv" "package:stats" "package:graphics" [4] "package:grDevices" "package:utils" "package:datasets" [7] "package:methods" "Autoloads" "package:base"> loadedNamespaces()[1] "base" "graphics" "grDevices" "grid" "lattice" "methods" [7] "stats" "utils"> # zoo is gone from attached package list and loadedNamespaces > # but numeric method for as.Date from zoo is still registered > as.Date(1)[1] "1970-01-02" On 3/26/07, gyadav at ccilindia.co.in <gyadav at ccilindia.co.in> wrote:> > Hi All > > what is the command to give me the listing of the loaded packages.
