Records the facts a replicator needs to rebuild the session: R version, platform, operating system, a UTC timestamp, and the versions of the requested packages.

Usage

capture_environment(packages = loadedNamespaces())

Arguments

packages: Character vector of package names to record. Defaults to every currently loaded namespace.

Value

A list with r_version, platform, os, captured_utc, and packages (a named character vector of versions).

Examples

# Record specific packages' versions alongside the session facts.
env <- capture_environment(c("stats", "utils"))
env$r_version
#> [1] "4.6.1"
env$os
#> [1] "Linux 6.17.0-1022-azure"
env$packages          # named character vector of versions
#>   stats   utils 
#> "4.6.1" "4.6.1" 

# Default captures every currently loaded namespace.
names(capture_environment())[1:4]
#> [1] "r_version"    "platform"     "os"           "captured_utc"
