Make plots from the output of the function calculateIDR
1 | plotIDR(chipTuple, idrCutoff = 0.01)
|
chipTuple |
one item of the return value of \calccalculateIDR |
idrCutoff |
peaks with an IDR greater than this cut-off are colored red in the scatter plot |
The output of calculateIDR()
is a list of tuples of ChIP samples.
plotIDR()
draws plots which compare the two members of a tuple.
For every tuple six plots are generated:
- number of peaks in common as a function of the number of _all_ significant peaks
- slope of the previous plot
- number of peaks in common as a function of the number of _matched_ significant peaks
- slope of the previous plot
- IDR as a function of the number of significant peaks
- scatter plot of ranked peaks of the ChIP samples
Refer to Qunhua Li et al (2011) for an explanation on how to interpret
the plots.
