[R] memisc output to latex

[michele]

Hi,
I am trying to output a table in a Latex format with write.mtable.
This is my code:

h.summary <- mtable("linear" = hlm, "quadratic" = hqd,
summary.stats=c("R-squared","adj. R-squared", "p"))
h.summary <- relabel(h.summary, "J" = "J", "I(J^2)" = "J^2")
write.mtable(h.summary, forLatex=TRUE, file="hsummary.tex")

The result is a nice text table of this format

===================================
                 linear   quadratic
-----------------------------------
(Intercept)      0.095***  0.061***
                (0.001)   (0.001) 
J          1.185***  2.319***
                (0.009)   (0.014) 
J^2                 -1.392***
                          (0.016) 
-----------------------------------
R-squared         0.768     0.899 
adj. R-squared    0.768     0.898 
p                 0.000     0.000 
===================================

but no latex output whatsoever.
Where am I wrong?
