R Documentation

Make Functions That Wrap Text in HTML Tags

Description

Helper functions to generate functions to use as slots for the StyleHtml@funs classes. These are functions that return functions.

Usage

tag_f(tag, class = character(), style = character())

div_f(class = character(), style = character())

span_f(class = character(), style = character())

cont_f(class = character())

Arguments

tag	character(1L) a name of an HTML tag
class	character the CSS class(es)
style	named character inline styles, where the name is the CSS property and the value the value.

Details

tag_f and related functions (div_f, span_f) produce functions that are vectorized and will apply opening and closing tags to each element of a character vector. container_f on the other hand produces a function will collapse a character vector into length 1, and only then applies the tags. Additionally, container_f already comes with the “diffobj-container” class specified.

Value

a function that accepts a character parameter. If applied, each element in the character vector will be wrapped in the div tags

Note

inputs are assumed to be valid class names or CSS styles.

Examples

Run examples

## Assuming class 'ex1' has CSS styles defined elsewhere
tag_f("div", "ex1")(LETTERS[1:5])
## Use convenience function, and add some inline styles
div_f("ex2", c(color="green", `font-family`="arial"))(LETTERS[1:5])
## Notice how this is a div with pre-specifed class,
## and only one div is created around the entire data
cont_f()(LETTERS[1:5])
