I have a xtable generated in R/Sweave that I would like displayed in portrait mode in a pdf. The spaces in the spacedSeq should properly align the sequences.

How can I force this to be in a monospace font. I can use XeteX if necessary but I don't know what fonts are available to me from my TeXlive installation on OS X.

a subset of the table below:

Welcome to TeX.sx! Not sure if I understand you correct. The normal way to make unbreakable spaces (in any font) is to use ~. –  Martin Scharrer Nov 1 '11 at 18:15

This requires the array package:

\usepackage{array}

Then you can use the >{...} syntax for adding declarations for one column; spaces not to be ignored are obtained by ~

\begin{tabular}{rl>{\ttfamily}llrrrrrr}
  \hline
 & rname & \normalfont spacedSeq & edits & RB494N & RB494T & RB495N & RB495T & RB498N & RB498T \\
  \hline
 1 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAA & 6:T 25:G &   1 &   0 &   0 &   0 &   0 &   0 \\
 2 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAGT & 6:T &   7 &   5 &  21 &   4 &   5 &   2 \\
 3 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAGTT & 6:T &  14 &  16 & 113 &  20 &  30 &   4 \\
 4 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAGTTA & 6:T 28:T &   2 &   1 &   8 &   0 &   0 &   0 \\
 5 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAGTTG & 6:T 28:T &   1 &   0 &   1 &   1 &   1 &   0 \\
 6 & hsa-let-7a-1 & AGAGGTAGTAGGTTGTATAGTTGT & 6:T 28:T &   1 &   0 &   0 &   0 &   0 &   0 \\
 7 & hsa-let-7a-1 & AGATGTAGTAGGTTGTATAGT & 6:T 9:G &   1 &   0 &   2 &   0 &   0 &   0 \\
 8 & hsa-let-7a-1 & ~~AGGTAGTAGGTTGTATAGT &  &   5 &   0 &   0 &   0 &   8 &   1 \\
 9 & hsa-let-7a-1 & ~~AGGTAGTAGGTTGTATAGTTT &  &   1 &   0 &   0 &   0 &   0 &   0 \\
10 & hsa-let-7a-1 & ~~AGGTAGTGGGTTGTATAGT & 15:A &   1 &   0 &   0 &   0 &   0 &   0 \\

One has to override the \ttfamily declaration in the header, which can be done by

\normalfont spacedSeq

or

\multicolumn{1}{l}{spacedSeq}

You may want to have the heading spacedSeq non-monospaced. The additional column declaration can be overridden using \multicolumn{1}{l}{spacedSeq}. –  Werner Nov 1 '11 at 19:07
    
@Werner I forgot that! Thanks. –  egreg Nov 1 '11 at 19:09
