Print HTML markup as readable text

Renders an "html" object as text in the console: tags are stripped or translated (<sub>/<sup> become _/^, <b>/<strong>/<i>/<em> become bold/italic via ANSI codes), common HTML entities ( , β, ...) are decoded, and <table> blocks are rendered as aligned text tables.

Usage

# S3 method for class 'html'
preview(x, ...)

Arguments

x

an object of class "html"

...

further arguments, currently unused (kept for consistency with print())

Value

x, invisibly

Details

If output does not support ANSI styling, bold/italic markup is rendered as plain text (handled automatically by cli).

m <- matrix(c(12.3, 4.56, 7.8, 91.2), nrow = 2,
            dimnames = list(c("a", "b"), c("mean", "sd")))
preview(toHtmlTable(m))
#>  | mean | sd
