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.Date Error 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, [EMAIL PROTECTED] <[EMAIL PROTECTED]> wrote: > > Hi All > > what is the command to give me the listing of the loaded packages.
