correlation: Correlation

In audreyqyfu/dagr: Generate and analyze data for direced acyclic graphs

Description

Calculates the correlation between two gene expression vectors at all levels of the genotype. In addition it calculates the correlation between the two genes at each level of the genotype.

Usage

correlation(t1, t2, V)

Arguments

t1	Gene expression vector.
t2	Gene expression vector.
V	Genotype vector.

Value

This function returns a dataframe where the first column is the correlation of T1 and T2 for all values of V, the second column is the correlation of T1 and T2 when V = 0, the third column is the correlation of T1 and T2 when V = 1, and the fourth column is the correlation of T1 and T2 when V = 2.

Examples

Model1 <- simulateData(N = 100,
                       p = 0.43,
                       seed = 338,
                       model = 'model1',
                       parameters = list(b0.1 = 0, b1.1 = 1, b0.2 = 0, b1.2 = 1, sd.1 = 1, sd.2 = 1, rho = 0.72))

correlation(Model1[, 1], Model1[, 2], Model1[, 3])
