I'd like an en dash - now.

Quotes need to be entered 'precisely'.

Footnotes can't have spaces before. \footnote{And should be full sentences}

We shouldn't refer to section 1 by typing out the literal cross-reference.

\section{Consitent labels are a good custom}\label{good-customs}

And English spacing dictates sentence spacing HERE. Otherwise the spacing looks strange.

Here the mismatched parentheses are obvious. (But it's not always the case.

And \LaTeX{} won't raise an error.

check_dashes(eg)

## Dash likely masquerading as hyphen. Use -- for a dash.
## <U+2716> 5: As always, visually check the result in the PDF.I'd like an en dash - now.

## IMPORTANT: make sure you are replacing a hyphen with two hyphens, not a unicode dash  –

## Error in rmarkdown::render("C:/Users/hughp/Documents/TeXCheckR/README.Rmd", : Single hyphen surrounded by spaces. This is likely a hyphen masquerading as dash. Use -- for a dash.

## IMPORTANT: make sure you are replacing a hyphen with two hyphens, not a unicode dash  –
## If you're not sure, reenter as two hyphens from the keyboard (rather than just appending a hyphen at the end). As always, visually check the result in the PDF.
check_quote_marks(eg)
##
## Closing quote used at beginning of word. Use a backtick for an opening quote, e.g. The word ossifrage' is quoted.

check_literal_xrefs(eg)
##
## Hard-coded xref in document.
## <U+2716> 11: We shouldn't refer to section 1 by typing out the literal cross-reference.
## All xrefs need to use \Cref or \Vref (or \Chapref for cross-references to chapters). If you need to use this phrase, you can use a non-breaking space e.g. 'Section~81 of the Constitution.
