addBins {epistack} | R Documentation |
Add an optional bin
metadata column to gr
,
to serve as annotations
for the epistack plots.
addBins(gr, nbins = 5L, bin = NULL)
gr |
a GRanges object. |
nbins |
an integer number, the number of bins. |
bin |
a vector containing pre-determined bins, in the same
order as |
nbins
is taken into account only if bin
is NULL
.
gr
should be sorted first, usually with the
addMetricAndArrangeGRanges()
function. addBin(gr, bin = vec)
is equivalent to
gr$bin <- vec
, while
addBin(gr, nbins = 5)
will create 5 bins of equal size based on
gr
order.
the gr
GRanges object with a new bin
metadata column
data("stackepi") addBins(stackepi) # 3 bins instead of 5 addBins(stackepi, nbins = 3) # assign bins using a vector addBins(stackepi, bin = rep(c("a", "b", "c"), length.out = length(stackepi)))
