## S3 method for class 'scantwoperm' subset(x, repl, lodcolumn, ...) ## S3 method for class 'scantwoperm' x[repl, lodcolumn]
x |
Permutation results from
scantwo , 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. |
The input scantwo
permutation results, but with only the specified
subset of the data.
