Escape HTML special characters

Replaces the three characters that would otherwise be read as markup. Use it on any text of unknown origin – a variable label, a file name, a user-supplied caption – before pasting it into HTML or XML.

Usage

escapeHtml(x, attribute = FALSE)

Arguments

x

a character vector

attribute

logical; also escape single and double quotes

Value

a character vector of the same length

Details

Quotes are escaped as well when attribute = TRUE, which is required for text placed inside an attribute value rather than between tags.

#> [1] "Anteil &lt; 5% &amp; steigend"
escapeHtml('say "hi"', attribute = TRUE)
#> [1] "say &quot;hi&quot;"
