Extended Information About the Current R Session

Description

Collect (and print) information about the current R session and environment, using sessionInfo() and more mostly low-level and platform dependent information.

isRshared() is a utility called from sessionInfoX().

Usage

sessionInfoX(pkgs = NULL, list.libP = FALSE, extraR.env = TRUE)

## S3 method for class 'sessionInfoX'
print(x, locale = TRUE, RLIBS = TRUE, Renv = TRUE, ...)

isRshared(platform = .Platform)

Arguments

`pkgs`	`NULL` (default), `TRUE` or a `character` vector of R package names, whose `packageDescription()`s are wanted. No packages by default, `TRUE` takes all currently loaded pkgs.
`list.libP`	a logical indicating if for all `.libPaths` entries, the files should be listed via `list.files`.
`extraR.env`	logical indicating if all environment variables should be recorded which start with `"R_"` or `"_R_"`.

`x`	typically the result of `sessionInfoX()`.
`locale`	logical, passed to `print.sessionInfo()` indicating if the locale information should be printed.
`RLIBS`	logical indicating if the information about R_LIBS should be printed.
`Renv`	logical indicating if the information about R environment variables should be printed.
`...`	passed to `print` methods.

platform

a list “like” .Platform.

Value

For isRshared(), a logical indicating if R has been installed as “shared”, i.e., linked to ‘libR*’ shared library.

For sessionInfoX(), an object of S3 class "sessionInfoX", a list with components (there may be more, experimental and not yet listed here):

`sInfo`	simply the value of `sessionInfo()`.
`sysInf`	the value of `Sys.info()`.
`capabilities`	the value of `capabilities()`.
`extSoft`	for R 3.2.0 and newer, the value of `extSoftVersion()`.
`grSoft`	for R 3.2.0 and newer, the value of `grSoftVersion()`.
`tclVersion`	for R 3.2.0 and newer and when tcltk is loaded, the Tcl version (`tclVersion()`).
`LAPACK`	for R 3.0.3 and newer, the value of `La_version()`.
`pcre`	for R 3.1.3 and newer, the value of `pcre_config()`.
`pkgDescr`	If `pkgs` was non-empty, a named `list` of `packageDescription()`s for each entry in `pkgs`.
`libPath`	the value of `.libPaths()`.
`RLIBS`	a `character` vector of entries from `Sys.getenv("R_LIBS")`, typically very similar to the `libPaths` component.
`n.RLIBS`	simply a `normalizePath()`ed version of `RLIBS`.
`R.env`	a named character vector with the “important” R environment variables `R_ENVIRON`, `R_PROFILE`, `R_CHECK_ENVIRON`.
`xR.env`	if `extraR.env` was true, a named character vector of “all R related” environment variables, as specified in `extraR.env`'s description above.
`shared`	(not available on Windows, where it is conceptually always true:) `logical` indicating if the version of R is “shared”.

Examples

six0 <- sessionInfoX()
six0$shared # useful (for some, e.g., MM) on Unix alikes

sixN <- sessionInfoX("nlme", list.libP = TRUE)
sixN # -> print() method for "sessionInfoX"
names(sixN)
str(sixN, max = 1)# outline of lower-level structure
str(sixN$pkgDescr) # list with one component "nlme"
