Kinship coefficient to cM
Description
"Converts" a kinship coefficient to put on the same scale as shared cM using the formula
cm <- pmin(3560, 4*pmax(0, k)*3560).
Usage
kin2cm(k)
Arguments
k
Kinship coefficient (numeric, typically between 0 and .5, although KING can produce values <0).
Value
A vector of numeric estimated cM, ranging from 0-3560.
