---+++ TDT2locus: An R program for two-locus TDT analysis URL of this page: [[http://biostat.mc.vanderbilt.edu/TDT2locus][http://biostat.mc.vanderbilt.edu/TDT2locus]] This [[%ATTACHURL%/TDT2L.r][program]] has two functions. The function =readin()= is for reading in data from a file and processing data into a format that can be used by the main analysis program, =TDT2L()=. The input data file should have *one title line and three columns*: family ID, gene 1 geneotype, gene 2 genotype. Genotypes should be coded as 0, 1, 2. Missing data should be denoted as a dot. The families should be sorted so that family members are clustered together, with the first two members as the parents and the other members as the offspring. A sample data file looks like this: <verbatim> family G1 G2 100501 1 1 100501 0 1 100501 0 1 100501 1 1 100701 0 2 100701 1 1 100701 1 . 100701 0 1 200601 0 1 200601 0 1 200601 0 1 1001201 . 1 1001201 . 2 1001201 . 1 1001201 . 2 1001501 1 0 1001501 1 0 1001501 1 0 1001801 1 0 1001801 0 2 1001801 1 1 1001801 1 1 </verbatim> <!-- * Set ALLOWTOPICCHANGE = ChunLi * Set TOPICLAYOUTURL = /twiki/pub/Main/ChunLi/ChunLiLayout.css * Set TOPICSTYLEURL = /twiki/pub/Main/ChunLi/ChunLiStyle.css -->
