xVisKernels

R Documentation

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 $\lambda$.

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, $h_{ds}(t)={1-{d_{gs}/D}\lambda}*(d_{gs} \le D)$

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

• For "rapid decay" kernel, $h_{ds}(t)={{1-d_{gs}/D}^\lambda}*(d_{gs} \le D)$
