[R] two-sided p-value?

Dear all,

I am a little bit confused because of the returned p-value by summary.lm and
also summary.rq

I thought if the pvalue is <= 0.05 the difference is significant. But the R
help says it is a two-sided pvalue. So does that mean the pvalue has to be
<= 0.025 and >= 0.975?

Best, Laura
