Description Creating Objects Slots Methods Author(s) See Also Examples

Description

Container for data that represent a receiver-operator-characteristic curve, and that were generated from the data of the annotated positive and negative controls in a scored cellHTS object.

Creating Objects

new("ROC")

ROC(object, positives, negatives) with object being an cellHTS instance.

Slots

name:

a character of length 1 with the name of the experiment from which the ROC object derives.

assayType:

a character of length 1 with the type of screenning assay. Possible values are: "one-way assay" and "two-way assay".

TP:

a vector of integers of length 1000.

FP:

a vector of integers of length 1000.

posNames:

a character vector with the name of the positive controls.

negNames:

a character vector with the name of the negative controls.

Methods

show

Print a summary of the object.

plot

Plot the ROC curve corresponding to the object.

lines

Line plot of the ROC object.
