Consistency of the mononuclear cell gate across aliquots. The plot shows the consistency of the MNC population across aliquots (coresampleid). The plot type is bwplot, and the formula for generating this output is coresampleidproportion, while the qaCheck was generated with proportioncoresampleid. Additional lattice plot arguments to generate a vertical boxplot layout are passed through the @par slot of the qaTask object. Note that there is no stratification variable. The bwplot plot type implies a grouping using the coresampleid variable (defined in the study metadata). Boxplots are generated for each level of coresampleid and outlier calls (red boxes and points) are made within each group as well as between groups (i.e., identifying groups with larger than expected variability). The population for this qaTask is MNC, the mononuclear cell gate.
