gespeR (version 1.4.2)

gespeR-class: gespeR

Description

Class that represents a gespeR model. It contains a SSP Phenotypes and TargetRelations representing a siRNA knockdown experiment. When the model is fitted, it additionaly contains estimated GSP Phenotypes.

Usage

gespeR(phenotypes, target.relations, ...)
## S3 method for class 'Phenotypes,TargetRelations':
gespeR(phenotypes, target.relations,
  mode = c("cv", "stability"), alpha = 0.5, nbootstrap = 100,
  fraction = 0.67, threshold = 0.9, EV = 1, weakness = 0.8,
  ncores = 1, ...)
## S3 method for class 'numeric,Matrix':
gespeR(phenotypes, target.relations, ...)

Arguments

phenotypes

The siRNA-spefic phenotypes. Single object for univariate phenotypes and list of Phenotypes objects for multivariate phenotypes.

target.relations

The siRNA-to-gene target relations

...

Additional arguments

mode

fraction

The fraction for each bootstrap sample

threshold

The selection threshold

EV

The expected value of wrongly selected elements

weakness

The weakness parameter for randomised lasso
