Nothing
A quantilequantile plot can be used to compare a sample of pvalues to the uniform distribution. But when the dataset is big (i.e. > 1e4 pvalues), plotting the quantilequantile plot can be slow. geom_QQ uses all the data to calculate the quantiles, but thins it out in a way that focuses on points near zero before plotting to speed up plotting and decrease file size, when vector graphics are stored.
