Value
An object of class "sessionInfo" which has print and
toLatex methods. This is a list with components
a list, the result of calling R.Version().
a character string describing the platform R was built under. Where sub-architectures are in use this is of the form platform/sub-arch (nn-bit).
a character string describing the OS and version which it is running under (as distinct from built under). This attempts to name a Linux distribution and give the OS name on an Apple Mac.
a character string, the result of calling
options("matprod").
a character string, the result of calling
extSoftVersion()["BLAS"].
a character string, the result of calling
La_library().
a character string, the result of calling
Sys.getlocale().
a character vector of base packages which are attached.
(not always present): a character vector of other attached packages.
(not always present): a named list of the results of
calling packageDescription on packages whose
namespaces are loaded but are not attached.
Note
The information on ‘loaded’ packages and namespaces is the current version installed at the location the package was loaded from: it can be wrong if another process has been changing packages during the session.
How OSes identify themselves and their versions can be arcane: where
possible running uses a human-readable form.
Windows may report unexpected versions: see the help for
win.version.
