convAASeq2mass

Molecular mass for amino-acids

This function calculates the molecular mass of one-letter code amion-acid sequences.

convAASeq2mass(
  x,
  massTy = "mono",
  seqName = TRUE,
  silent = FALSE,
  callFrom = NULL
)

`x`	(character) aminoacid sequence (single upper case letters for describing a peptide/protein)
`massTy`	(character) default 'mono' for mono-isotopic masses (alternative 'average')
`seqName`	(logical) optional (alternative) names for the content of 'x' (ie aa seq) as name (always if 'x' has no names)
`silent`	(logical) suppress messages
`callFrom`	(character) allow easier tracking of message(s) produced

vector with masses for all amino-acids (argument 'massTy' to switch form mono-isotopic to average mass)

convAASeq2mass(c("PEPTIDE","fPROTEINES"))
pep1 <- c(aa="AAAA",de="DEFDEF")
convAASeq2mass(pep1,seqN=FALSE)
