An object of this class contains (a subset) the following elements:
counts
(numeric) Binned read counts as non-negative
integers in {0,1,2,...}. An object with only this field is
created by binReadCounts().
fit
(numeric; optional) Loess fit of "count" signals as
doubles. Normally, these should all be positive values, but a
small number of edge case bins might contain negatives, especially
when fitting unfiltered data. This element is added after calling
estimateCorrection().
Missing values
The bin data (assay data) may contain missing values.
