| base.freq {ape} | R Documentation |
This function computes the relative frequencies (i.e. percentages) of the four DNA bases (adenine, cytosine, guanine, and thymidine) from a sample of sequences.
base.freq(x)
x |
a vector, a matrix, a data frame, 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 table of relative frequencies with the names "a", "c",
"g", and "t".
