spearmanCorrMethod: Spearman's rho statistic of two profiles

In similaRpeak: Metrics to estimate a level of similarity between two ChIP-Seq profiles

Description

Calculate and return the Spearman's rho statistic of two profiles. If one profile has a standard deviation inferior to the threshold, the function returns NA. When no complete element pair are present, NA is returned.

Usage

spearmanCorrMethod(profile1, profile2, threshold = 1e-08)

Arguments

profile1	a vector of numeric values, the first profile containing the alignment depth for each position. The profile1 and profile2 should have the same length.
profile2	a vector of numeric values, the second profile containing the alignment depth for each position. The profile1 and profile2 should have the same length.
threshold	a numeric, the minimum standard deviation accepted to calculate a ratio. Default = 1e-8

Value

The calculated ratio or NA if one profile has a standard deviation inferior to the threshold. If profiles have no complete element pair, NA is returned.
