Keywords

Usage
where(x, pattern)
Arguments
x
an object of class "DNAbin".
pattern
a character string to be searched in x.
Details

If 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 each sequence.

Patterns may be overlapping. For instance, if pattern = "tata" and the sequence starts with `tatata', then the vector returned will be c(1, 3).

Value

  • a vector of integers or a list of such vectors.
