Usage

Go into the reactnb directory and run Shiny the usual way:

R -e "shiny::runApp(launch.browser=TRUE)"

• Click commands to prepopulate the input bar with them
• Drag output to detach them
• Drag detached commands to trash to delete
• Click the trash to undelete trashed commands (it's a stack, one restored per click)

Keyboard shortcuts:

• Ctrl+K - Clear non-detached commands
• Ctrl+Shift+K - Clear all commands
• Up/Down - Navigate command history
• Ctrl+G - If commands go past the top or left of the screen, Ctrl+G will gather them back so they're visible
• Ctrl+H - Hide all input commands and nondetached output

Magic prefixes:

• [print] - The default
• [plot] - plot (also looks for plot, hist, ggplot, qplot in the command and assumes plotting)
• [table] - data frames rendered using xtable
• [ui] - UI (e.g. numericInput or whatever)
• [html] - HTML using Shiny builder functions (or HTML() for raw HTML, includeMarkdown(), includeHTML(), etc.)
• [text] - Display as string instead of print (e.g. [text] "foo" would display foo instead of [1] "foo")
