[R] multcomp package

[li li]

Hi all,
  After fitting a random slope and random intercept model using lme
function, I want
to test whether each of the fixed slopes is equal to zero (The output of
model is below).
Can this be done (testing each individual slope) using multcomp package?
  Thanks much for the help.
