In qtl: Tools for Analyzing QTL Experiments

Subsetting permutation test results

Description

Pull out results for a specified set LOD columns from permutation results from scanone.

Usage

## S3 method for class 'scanoneperm'
subset(x, repl, lodcolumn, ...)
## S3 method for class 'scanoneperm'
x[repl, lodcolumn]

Arguments

x	Permutation results from scanone, run with n.perm>0.
repl	A vector specifying which permutation replicates to keep or (if negative) omit.
lodcolumn	A vector specifying which LOD columns to keep or (if negative) omit. These should be between 1 and the number of LOD columns in the input x.
...	Ignored at this point.

Value

The input scanone permutation results, but with only the specified subset of the data.
