Create a histogram for the variance within replicates for each pgRNA

Source: R/plots-qc.R

This function uses pivot_longer to rearrange the data for plotting, finds the variance for each pgRNA construct (using row number as a proxy) and then plots a histogram of these variances

qc_variance_hist(
  gimap_dataset,
  filter_replicates_target_col = NULL,
  wide_ar = 0.75
)

Arguments

gimap_dataset

The special gimap_dataset from the `setup_data` function which contains the transformed data

filter_replicates_target_col

default is NULL; Which sample columns are replicates whose variation you'd like to analyze; If NULL, the last 3 sample columns are used

wide_ar

aspect ratio, default is 0.75

Value

a ggplot histogram

Examples

if (FALSE) {
gimap_dataset <- get_example_data("gimap")
qc_variance_hist(gimap_dataset)
}
