R help - May 2012 - Does aov produce one-sided or two-sided p-values?

Hi -

Hopefully this is an easy question.   In SPSS, when I'm testing a
directional hypotheses using an ANOVA (GLM), I can divide the p-value by 2
because SPSS reported two-sided p-values?  Is this approach still legit
when I'm using aov in R?

Thanks,

Matt
