Very simple implementation that will fail if there are any “>” in the
HTML that are not closing tags, and assumes that HTML entities are all one
character wide. Also, spaces are counted as one width each because the
HTML output is intended to be displayed inside <PRE> tags.
Usage
nchar_html(x, ...)
Arguments
x
character
...
unused for compatibility with internal use
Value
integer(length(x)) with number of characters of each element
