Warning messages:
1: In markers_distribution(data_long, case_class = "A") :
  boxplot_lim is not set. Boxplot may be difficult to interpret due to outliers. You should set an appropriate y axis limit.
2: In markers_distribution(data_long, case_class = "A") :
  In $Coord object you will see only the signal threshold values at which SE>=0 and SP>=0 by default. If you want to change this limits, please set min_SE and min_SP
3: In markers_distribution(data_long, case_class = "A") :
  You can adjust density plot zoom by setting y_lim and x_lim
4: Using `size` aesthetic for lines was deprecated in ggplot2 3.4.0.
