xVisKernels: Function to visualise distance kernel functions

In hfang-bristol/XGR: Exploring Genomic Relations for Enhanced Interpretation Through Enrichment, Similarity, Network and Annotation Analysis

Function to visualise distance kernel functions

Description

xVisKernels is supposed to visualise distance kernels, each of which is a decaying function of: i) the relative distance d_{gs} between the gene g and the SNP s, and ii) the decay exponent λ.

Usage

xVisKernels(exponent = 2, newpage = TRUE)

Arguments

exponent	an integer specifying decay exponent. By default, it sets to 2
newpage	logical to indicate whether to open a new page. By default, it sets to true for opening a new page

Value

invisible

Note

There are five kernels that are currently supported:

• For "slow decay" kernel, h_{ds}(t)={1-{d_{gs}/D}λ}*(d_{gs} ≤ D)

• For "linear decay" kernel, h_{ds}(t)={1-d_{gs}/D}*(d_{gs} ≤ D)

• For "rapid decay" kernel, h_{ds}(t)={{1-d_{gs}/D}^λ}*(d_{gs} ≤ D)
