Making publication-ready tables with xtable

When you use R at the command-line, the textual output is limited by the medium: one monospaced font, with no typesetting of any kind. That’s great when you’re doing exploratory analysis, but what about when you want to include R output in a report or publication? In other words, what if you want to convert this Analysis of Variance table:

 
       Df Sum Sq Mean Sq F value  Pr(>F)  
sex      1  75.4  75.37 0.3793 0.539478  
ethnicty   3 2572.1 857.38 4.3147 0.006781 **
sex:ethnicty 2  298.4 149.22 0.7509 0.474767  
Residuals  93 18480.0 198.71
