compute.gc {Ringo} | R Documentation |
Simple auxiliary function to compute the GC content of a given set of DNA sequences, such as microarray probe sequences.
compute.gc(probe.sequences, digits = 2)
probe.sequences |
character vector of DNA or probe sequences of which the GC content is to be computed |
digits |
integer specifying the desired precision |
a numeric vector with sequence-wise GC contents; the names of this
vector are the names of the supplied probe.sequences
.
