a set of motifs, either a list of frequency
matrices, or a list of PWM objects. If frequency matrices
are given, the background distribution is fitted from
bg.seq.
organism
either a name of the organisms for which
the background should be compiled (supported names are
"dm3", "mm9" and "hg19"), or
a BSgenome object (see BSgenome package).
bg.seq
a set of background sequence (either this
or organism needs to be specified!). Can be a DNAString
or DNAStringSet object.
quick
if to do the fitting only on a small subset
of the data (only in combination with organism).
Useful only for code testing!
pseudo.count
the pseudo count which is shared
between nucleotides when frequency matrices are given
Value
a list of ecdf objects (see help page for
ecdf for usage).
