Repeating tdt function on thousands of variables
...Thereafter
each variable is a specific locus or marker. The variables are named by a
pattern such as "Genotype.nnnnn" with nnnnn corresponding to a number which
is the name or id of the locus.
I am able to get the tdt to run by each locus. >tdt(Genotype.914186, PGWide,
famid, pid, fatid, motid, sex, affected )
Clearly I cannot type each locus in one at a time. Instead I want to loop it
but am not sure how to do it. I tried lapply but it did not really work.
The example in Dalgaard's book, >sapply( thuesen, mean, na. rm= T) seems to
work with basic functions but not with...

Reshaping genetic data from long to wide
Bottom Line Up Front: How does one reshape genetic data from long to wide?
I currently have a lot of data. About 180 individuals (some
probands/patients, some parents, rare siblings) and SNP data from 6000 loci
on each. The standard formats seem to be something along the lines of Famid,
pid, fatid, motid, affected, sex, locus1Allele1, locus1Allele2,
locus2Allele1, locus2Allele2, etc
In other words one human, one row. If there were multiple loci then the
variables would continue to be heaped up on the right. This kind of
orientation, shall be referred to as "wide".
Given how big m...
