hugo_save_investigation: Save variables and information about packages

In hugo4r/hugo: I'm your personal assistant!

Description

The hugo_save_investigation saves variables and versions of packages used in investigation. Data is stored in subfolder resources/session_name in two separate files: variables and packages. Restoring data and loading saved versions of packages could be done by using function hugo_continue_investigation.

Usage

hugo_save_investigation(variables = NULL, session_name = NULL,
  envir = .GlobalEnv)

Arguments

variables	a character vector containing names of important variables to be saved. By default variables = NULL, what means that all the variables in environment envir are saved.
session_name	name of directory in which the session will be saved. If session_name = NULL, the dafault name is set.
envir	an environment to search for objects to be saved. Global Environment by default.
