latex(x) returns an object of class "latex".  When you don't assign it, 
it prints.  The print method for "latex" objects tries to run latex and 
then display the resulting .dvi file.  (Or maybe it runs pdflatex and 
displays the .pdf file).

If you can't run latex, you can't print those objects.  That's why 
you're getting an error.
