As Ista said, you can use the p{}, m{} and b{} LaTeX column specifications
to create a table column that enforces a line wrap on it's contents. See:
http://en.wikibooks.org/wiki/LaTeX/Tables#The_tabular_environment
for full details.
However, one problem with using say, p{2in}, is that the text is set *fully
justified*. This means that the inter-word spacing in each line is expanded
so that the line fully occupies the allotted 2 inches of space. For some
tables the results are a typographical travesty.
The solution is to prepend a ">{justificationCommand}" to your column
specification, such as:
>{\centering}p{2in}
The justification commands you can use are :
\centering -> Centers wrapped text
\raggedright -> *left* aligns wrapped text
\raggedleft -> *right* aligns wrapped text
Remember to double the backslash if you are passing this command as an
argument in R.
This trick will cause a LaTeX compilation error if used to specify the
right-most column in a table, unless the hmisc latex() command produces
tables that use "\tabularnewline" to invoke table row breaks instead of
"\\".
Hope this helps.
