nonredDataFrame: Filter for unique elements

Description

nonredDataFrame filters 'x' (list of char-vectors or char-vector) for elements unique (to 'ref' or if NULL to all 'x') and of character length. May be used for different 'accession' for same pep sequence (same 'peptide_id'). Note : made for treating data.frames, may be slightly slower than matrix equivalent

Usage

nonredDataFrame(
  dataFr,
  useCol = c(pepID = "peptide_id", protID = "accession", seq = "sequence", mod =
    "modifications"),
  sepCollapse = "//",
  callFrom = NULL
)

Arguments

dataFr

(data.frame) main inpput

useCol

(character,length=2) comlumn names of 'dataFr' to use : 1st value designates where redundant values should be gathered; 2nd value designes column of which information should be concatenated

sepCollapse

(character) conatenation symbol

callFrom

(character) allow easier tracking of messages produced

Value

data.frame of filtered (fewer lines) with additional 2 columns 'nSamePep' (number of redundant entries) and 'concID' (concatenated content)

Examples

# NOT RUN {
df1 <- data.frame(cbind(xA=letters[1:5],xB=c("h","h","f","e","f"),xC=LETTERS[1:5])) 
nonredDataFrame(df1,useCol=c("xB","xC")) 
# }
