Package 'picClip'

Title: Paste Box Input for 'shiny'
Description: Provides a 'shiny' input widget, pasteBoxInput, that allows users to paste images directly into a 'shiny' application. The pasted images are captured as Base64 encoded strings and can be used within the application for various purposes, such as display or further processing. This package is particularly useful for applications that require easy and quick image uploads without the need for traditional file selection dialogs.
