[R] Parsing protein sequences

I have two files with peptide sequences. These two
have peptide sequences(obtained from tryptic and
semi-tryptic digestion using Mass spec analysis).
There are two columns :peptide sequence and protein
File 2 has both tryptic and semi-tryptic peptides and
File 1 has only semi-tryptic peptides. Is there a way
out that I can filter semi-tryptic peptides from
typtic ones. There are ~30,000 peptides in each file.
Please suggest if this can be done in R. I want to do
further analysis involving some statistics using R.
Thank you in advance.
File 1 (is a comma seperated file):
File 2 (comma seperated file):
