Re: [R] a very small query

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")

> 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"

?search
?sessionInfo

(sessionInfo massages the output of search() to show only packages).
