6.4 Some common LaTeX errors

Too deeply nested

Apparently this really means what it says. Maybe something not closing?

Float too large

Picture or table is too large to fit in available space on page. Ignore.

Overfull vbox

Means that something didn't really fit. May cause misformatting and ugliness. Ignore, it's only a warning.

Missing \ inserted

Automatic switch to math mode: char (e.g. underscore) only allowed in math mode was seen and LaTeX "helpfully" switches to math mode. Generally fixed either by eliminating the suspect character, enclosing text in < <tt: ...> > block, or some other form of escaping.

Twocolumn format: put twocolumn option to article or use multicol mode.

direct tex like

  just a \hspace{\fill} word

N.B. This example only renders decently on PDF (generated using the LaTeX backend).

For accurate freeform layout and positioning, try textpos placement
macros (http://purl.org/nxg/dist/textpos).
