sessionInfo {utils}R Documentation

Collect Information About the Current R Session

Description

Print version information about R, the OS and attached or loaded packages.

Usage

sessionInfo(package = NULL)
## S3 method for class 'sessionInfo'
print(x, locale = TRUE, ...)
## S3 method for class 'sessionInfo'
toLatex(object, locale = TRUE, ...)

Arguments

package

a character vector naming installed packages, or NULL (the default) meaning all attached packages.

x

an object of class "sessionInfo".

object

an object of class "sessionInfo".

locale

show locale information?

...

currently not used.

Value

An object of class "sessionInfo" which has print and toLatex methods. This is a list with components

R.version

a list, the result of calling R.Version().

platform

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).

running

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.

matprod

a character string, the result of calling options("matprod").

BLAS

a character string, the result of calling extSoftVersion()["BLAS"].

LAPACK

a character string, the result of calling La_library().

locale

a character string, the result of calling Sys.getlocale().

basePkgs

a character vector of base packages which are attached.

otherPkgs

(not always present): a character vector of other attached packages.

loadedOnly

(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.
