Task: Class Definition Understanding (ontology: Sciences/Computer_Science)

Which of the following definitions best describes 'nudge'?

A. Package for normalizing microarray data in single and multiple replicate experiments and fitting a normal-uniform mixture to detect differentially expressed genes in the cases where the two samples are being compared directly or indirectly (via a common reference sample)
B. Various wrapper functions that have been written to streamline the more common analyses that a core Biostatistician might see
C. The package contains functions for pre-processing Affymetrix data using the RMA+ and the RMA++ methods.
D. A prototype for a mechanism for specifying the types of parameters and the return value for an R function. This is meta-information that can be used to generate stubs for servers and various interfaces to these functions

Answer: Package for normalizing microarray data in single and multiple replicate experiments and fitting a normal-uniform mixture to detect differentially expressed genes in the cases where the two samples are being compared directly or indirectly (via a common reference sample)
