Strange Plot Appearance for p-values

[DarioS]

Am I using it improperly? If so, could you add an example of correct use to the vignette? Minimal reproducible example follows.

If genefilter needs installation.

if (!require("BiocManager", quietly = TRUE))
    install.packages("BiocManager")
BiocManager::install("genefilter")

Load the package. Simulate and test.

library(genefilter)
dataset <- sapply(1:1000, function(index) rnorm(20))
result <- colttests(dataset, factor(rep(c("No", "Yes"), length.out = 20)))

library(qqplotr)
ggplot(result, mapping = aes(sample = p.value)) + stat_qq_band() + stat_qq_line() + stat_qq_point()
