tooltip: Create a bootstrap tooltip

In RLumShiny: 'Shiny' Applications for the R Package 'Luminescence'

Create a bootstrap tooltip

Description

Create bootstrap tooltips for any HTML element to be used in shiny applications.

Usage

tooltip(
  refId,
  text,
  attr = NULL,
  animation = TRUE,
  delay = 100,
  html = TRUE,
  placement = "auto",
  trigger = "hover"
)

Arguments

refId	character (required): id of the element the tooltip is to be attached to.
text	character (required): Text to be displayed in the tooltip.
attr	character (optional): Attach tooltip to all elements with attribute attr='refId'.
animation	logical (with default): Apply a CSS fade transition to the tooltip.
delay	numeric (with default): Delay showing and hiding the tooltip (ms).
html	logical (with default): Insert HTML into the tooltip.
placement	character (with default): How to position the tooltip - top | bottom | left | right | auto. When 'auto' is specified, it will dynamically reorient the tooltip. For example, if placement is 'auto left', the tooltip will display to the left when possible, otherwise it will display right.
trigger	character (with default): How tooltip is triggered - click | hover | focus | manual. You may pass multiple triggers; separate them with a space.

Examples

# javascript code
tt <- tooltip("elementId", "This is a tooltip.")
str(tt)
