Details

One of the mechanisms used by the API for Boostrap JavaScript-components is an html elements' attributes. These attribute names are prefixed with "data-" or "aria-", depending on the function.

When expressed in html, attributes themselves have the properties:

  • Logical values are expressed as "true" or "false".

  • Time durations are expressed as number of milliseconds.

  • Vector (non scalar) values are expressed in a space-delimited list.

The purpose of this function is to let you express these values in ways familiar to you as an R user. For example:

  • Logical values can be expressed as logicals: TRUE or FALSE.

  • Time durations can be expressed using lubridate durations.

  • Vector (non scalar) values can be expressed as vectors.

Note that this returns a modified copy of the tag sent to it, so it is pipeable.
