sessionInfoX: Extended Information About the Current R Session

Description

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

Usage

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

Arguments

pkgs

an optional character vector of Rpackages, whose packageDescription()s are wanted.

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_".

Value

• 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().
• 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 Renvironment 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.

Examples

six0 <- sessionInfoX()
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"
