halfsibscan {lodplot} | R Documentation |
Generate results from an affected half-sib pair genome scan
halfsibscan(N = 100, grid = 1)
N |
is the number of affected half-sib pair families |
grid |
the distance between the (perfectly informative) scan markers |
Carried out the appropriate random walk on each chromosome to generate lod scores that would result if there were no trait loci segregating in the pedigrees sampled.
A data frame, containing:
|
the chromosome (1..22, X) |
|
the genetic map position on the chromosome |
|
the simulated lod score. |
