protseg(x, aa = c("A", "R", "N", "D", "C", "E", "Q", "G", "H", "I", "L", "K",
  "M", "F", "P", "S", "T", "W", "Y", "V"), k = 7)

Arguments

x

A character vector, as the input protein sequence.

aa

A character, the amino acid type. One of 'A', 'R', 'N', 'D', 'C', 'E', 'Q', 'G', 'H', 'I', 'L', 'K', 'M', 'F', 'P', 'S', 'T', 'W', 'Y', 'V'.

k

A positive integer, specifys the window size (half of the window), default is 7.

Value

A named list, each component contains one of the segmentations (a character string), names of the list components are the positions of the specified amino acid in the sequence.
