Base frequencies from DNA Sequences
This function computes the relative frequencies (i.e. percentages) of the four DNA bases (adenine, cytosine, guanine, and thymidine) from a sample of sequences.
- a vector, a matrix, or a list which contains the DNA sequences.
The base frequencies are computed over all sequences in the sample. All missing or unknown sites are discarded from the computations.
- A numeric vector stoting the relative frequencies with names
c("a", "c", "g", "t").
