Check labels
check_labels(filename, .report_error, check.chaprefs = TRUE)The LaTeX source file to check.
The function to provide context to the error.
(logical, default: TRUE) If TRUE, require all cross-references to use \Chapref.
NULL, invisibly if labels check out. An error otherwise.
Checks each label has a prefix and the prefix is one of the following:
fig:,
tbl:,
box:,
chap:,
sec:,
eq:,
subsec:,
subsubsec:,
para:
paragraph:.
Checks also that chapter labels are marked with chap:.
(N.B. although each label must have a prefix, it must not necessarily the right prefix;
for example, a table caption may have prefix tbl:.)
