Hello , i'm wondering if there is a way ( maybe a R package already developed ? ) to get the strand information (+ or - ) related to my peaks. Actually, it's a dataframe , with 3 columns , chr , start, end , i would like to add a strand columns with the right information .

Thank you

Peaks based on what? Something ike ChIP-seq? That would be unstranded as it is DNA-seq and DNA is double-stranded.
