Default Script to make sequences equal length

I would like to perform a motif analysis with my ChIP-Seq data on meme-suite.
The program requires me to put in sequences of equal length.
I have the nucleotide sequences from the regions where our protein of interest bound to in ChIP-Seq. These regions are of varying length.
I would like to make them of equal length by figuring out the sequence of greatest length and adding 'N's to both ends of the remaining sequences.
Anyone done this/has a R script?
Many thanks for your feedback in advance!
