R help - Feb 2008 - Is there a simple way to use one-way ANOVA comparing the means of groups?

Dear all,

I have finally managed to get a "Analysis of Variance Table":


Response: LogHand
                  Df     Sum     Sq Mean    Sq F value        Pr(>F)
Prey            3    5.3125     1.7708       20.672            2.066e-11 ***
Residuals  164    14.0488   0.0857

I want to compare the means of the four different groups, and see if
there is a difference. I searched for help, and think that maybe
Tukey(stats)  would be proper..?

Is there anyone that could give advice for to this?
