rugplotDonorTargetTest: rugplotDonorTargetTest

Description Usage Arguments Value See Also Examples

View source: R/rugplotDonorTargetTest.R

Description

This function is called by CellScoreReport to make a rugplot showing the CellScore of all test samples, in relation to the standards. Donor and target individual CellScore values are plotted in one horizontal lane, then test CellScore values are are in another horizontal lane. Z-score cutoffs based on the target standards are shown as dashed vertical lines.

Usage

1
rugplotDonorTargetTest(test.data, cellscore)

Arguments

test.data

a data.frame of CellScore values as calculated by CellScore(), for only plot group of test samples.

cellscore

a data.frame of CellScore values as calculated by CellScore().

Value

This function outputs the plot on the active graphical device and returns invisibly NULL.
