Yes, it's homework . . . delete now if desired . . . but I think it is an
interesting problem.
Running R 2.11.1, LaTeX on WinXP, via Sweave.
A drop1() object from a glm() produces, as part of its output, a string that
looks like this:
<none>
The trouble I run into is that running latex() on a drop1() object from
glm() produces a string that looks like this in the generated .tex file:
\textlessnone\textgreater
This gives an "undefined control sequence" error when compiling the .tex
file. I can just <ENTER> past the error, but the resulting .pdf file
contains just a greater-than symbol in the table where <none> is supposed to
appear.
If I go into the .tex file and manually insert a space, changng it to
\textless none\textgreater
the document compiles fine.
Reproducile example below. Any suggestions?
Thanks.
