Collect Information About the Current R Session

Description

Print version information about R 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 a print method. This is a list with components

`R.version`	a list, the result of calling `R.Version()`.
`platform`	a character string describing the platform. For recent versions where sub-architectures are in use this is of the form platform/sub-arch (nn-bit).
`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.

Examples

sessionInfo()
toLatex(sessionInfo(), locale=FALSE)
