In dereksonderegger/PepSeq: Tools for analyzing Peptide Sequencing results

View source: R/Pulldown_Import_Metadata.R

Internally, the PepSeq package keeps track of peptides via the protein column and the position within the protein. However, that isn't consistent with other programs so we need a way to associate the protein/position information with the library_member code, the actual peptide sequence, as well as the Accession number

  position_column = "Peptide.start", meta_columns = c("library_member",
  "Peptide.seq", "Accession"))

`file`	The input .csv, .xls, or .xlsx file. It can be a full path to a file or a relative path from the current working directory.
`protein_column`	A character string indicating which column denotes the protein.
`position_column`	A character string indicating which column corresponds to the position within a protein.
`meta_columns`	A vector of character strings indicating which columns contain metadata that should be stored.
