Find Sequence Motifs.
Return Position Indices of a Short Sequence Motif Within a Larger Sequence.
motif.find(motif, sequence)
motif |
a character vector of the short sequence motif. |
sequence |
a character vector of the larger sequence. |
The sequence and the motif can be given as a either a multiple or
single element character vector. The dot character and other valid
regexpr characters are allowed in the motif, see examples.
Returns a vector of position indices within the sequence where the motif was found, see examples.
