x |
An object of class scantwo, output from
scantwo. |
chr |
Optional vector specifying which chromosomes to keep.
This should be a vector of character strings referring to
chromosomes by name; numeric values are converted to strings. Refer to
chromosomes with a preceding - to have all chromosomes but those
considered. A logical (TRUE/FALSE) vector may also be used. |
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 object, but with only the specified
subset of the data.
