Saves R session information, including platform details, package versions, and optionally, a summary of objects in the session, to a text file.
Usage
save_session_info(out_directory = getwd(), session_info = NULL, prefix = "S")Arguments
- out_directory
Character. Directory path where the output file is saved. Defaults to the current working directory (
base::getwd()).- session_info
An optional tibble or data frame with object details (e.g., from
save_session()). If provided, details of objects (e.g., names and sizes in MB) are appended to the output file. Defaults toNULL.- prefix
Character. Prefix for the output file name. Defaults to
"S".
Examples
load_packages(fs)
# Save session info without object details
temp_dir <- fs::path_temp("save_session_info")
fs::dir_create(temp_dir)
save_session_info(out_directory = temp_dir)
#> Saving session info to:
#> /tmp/RtmpsRrw5J/save_session_info/S_20260511_0204.txt
saved_file <- list.files(
temp_dir, pattern = "S_.+txt$", full.names = TRUE) %>%
ecokit::normalize_path()
(saved_file <- saved_file[length(saved_file)])
