This function finds patterns in a single or a set of DNA sequences.
- an object of class
- a character string to be searched in
x is a vector, the function returns a single vector giving
the position(s) where the pattern was found. If
x is a matrix
or a list, it returns a list with the positions of the pattern for
Patterns may be overlapping. For instance, if
pattern = "tata"
and the sequence starts with `tatata', then the vector returned will
be c(1, 3).
- a vector of integers or a list of such vectors.
