Your attachment did not come through, most likely because it is not a 
type that is supported by the list.

Well I can't directly help you with your issue, since I don't know what 
error you're receiving, the reason this is happening is that when you 
don't assign the result of your latex call, the function 'print.latex' 
is getting called, which if I understand tries to compile the LaTeX 
output and display the result in a suitable viewer.  By assigning the 
results of the latex call in R, you stop this printing from happening.

As for what your issue is, I don't know since your attachment did not 
come through.
