solve.Pearson: Run the Pearson Solver

In PriceLab/trena: Fit transcriptional regulatory networks using gene expression, priors, machine learning

Run the Pearson Solver

Description

Given a PearsonSolver object, use the cor function to estimate coefficients for each transcription factor as a predictor of the target gene's expression level.

Usage

## S4 method for signature 'PearsonSolver'
run(obj)

Arguments

obj	An object of class PearsonSolver

Value

The set of Pearson Correlation Coefficients between each transcription factor and the target gene.

Examples

# Load included Alzheimer's data, create a TReNA object with Bayes Spike as solver, and solve
load(system.file(package="trena", "extdata/ampAD.154genes.mef2cTFs.278samples.RData"))
target.gene <- "MEF2C"
tfs <- setdiff(rownames(mtx.sub), target.gene)
pearson.solver <- PearsonSolver(mtx.sub, target.gene, tfs)
tbl <- run(pearson.solver)
