toComplex: Turning a DNA sequence into a vector of complex numbers
In anandhupresannan/biostrings: Efficient manipulation of biological strings

Description Usage Arguments Value Author(s) See Also Examples

The toComplex utility function turns a DNAString object into a complex vector.

1	toComplex(x, baseValues)

`x`	A DNAString object.
`baseValues`	A named complex vector containing the values associated to each base e.g. `c(A=1+0i, G=0+1i, T=-1+0i, C=0-1i)`

A complex vector of the same length as x.

DNAString

  seq <- DNAString("accacctgaccattgtcct")
  baseValues1 <- c(A=1+0i, G=0+1i, T=-1+0i, C=0-1i)
  toComplex(seq, baseValues1)

  ## GC content:
  baseValues2 <- c(A=0, C=1, G=1, T=0)
  sum(as.integer(toComplex(seq, baseValues2)))
  ## Note that there are better ways to do this (see ?alphabetFrequency)
