Description Usage Arguments Author(s) Examples
Makes formatted density plots from the posterior data frame(s) returned by CNVtest.binary
1 |
posterior |
The posterior distribution obtained from the CNVtools fitting algorithm, for example using CNVtest.binary |
hist.or.dens |
Either 'histogram' or 'density' to plot the data as an histogram or using a kernel density estimator |
batch |
character vector (usually of length 1, but not always), designing the batches one wants to plot. |
freq |
This argument is only relevant when hist.or.dens='histogram' (the default). It matches the argument freq of the hist function. With freq = FALSE frequencies, and not raw counts, are shown in the histogram. |
... |
Usual arguments passed to the hist function, including main or breaks for example. |
