  • rs_save_all: save all editing document when 'RStudio' is running
  • rs_exec: run job in 'RStudio', otherwise use Rscript
  • ask_yesno, ask_or_default also uses 'RStudio' dialogue
  • other functions starting with rs
• add_to_session stores key-value pairs in shiny reactive sessions
• clear_env clear elements in environments or fastmap2 instances
• do_nothing literally does nothing
• shiny_is_running returns whether current context is within a shiny app
• test_farg tests whether a function contains certain arguments
• capture_expr captures outputs when evaluating expression and returns a string
• get_dev_attr get attributes from graphic devices
• print_directory_tree generates directory tree as text

Minor Changes
