[R] 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 [[alternative HTML version dele
