Filter for unique elements
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
nonredDataFrame(
dataFr,
useCol = c(pepID = "peptide_id", protID = "accession", seq = "sequence", mod =
"modifications"),
sepCollapse = "//",
callFrom = NULL
)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 |
data.frame of filtered (fewer lines) with additional 2 columns 'nSamePep' (number of redundant entries) and 'concID' (concatenated content)
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"))Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
