Create a histogram for the pgRNA log2 CPMs, faceted by sample

This function uses pivot_longer to rearrange the data for plotting and then plots sample specific histograms of the pgRNA cpm's

qc_sample_hist(gimap_dataset, wide_ar = 0.75)

Arguments

gimap_dataset: The special gimap_dataset from the `setup_data` function which contains the transformed data
wide_ar: aspect ratio, default is 0.75

sample_cpm_histogram a ggplot

if (FALSE) { # \dontrun{
gimap_dataset <- get_example_data("gimap")
qc_sample_hist(gimap_dataset)
} # }
