split a sequence into sub-sequences
Split a sequence into sub-sequences of 3 (the default size) with no overlap between the sub-sequences.
splitseq(seq, frame = 0, word = 3)
seq |
a vector of chars |
frame |
an integer (0, 1, 2) giving the starting position to split the sequence |
word |
an integer giving the size of the sub-sequences |
This function returns a vector which contains the sub-sequences.

# To obtain the codon sequence in frame 0:

stopifnot(identical(splitseq(cds),
c("aac", "gtt", "gca", "ggt", "cgc", "tcg", "cta", "cgt", "agc", "tac", "tgt")))

# Show the effect of frame and word with a ten char sequence:
