Combining 2 columns into 1 column many times in a very large dataset
...ficient.
Here is a toy example of the data structure:
pop = data.frame(status = rbinom(n, 1, .42), sex = rbinom(n, 1, .5),
age = round(rnorm(n, mean=40, 10)), disType = rbinom(n, 1, .2),
rs123=c(1,3,1,3,3,1,1,1,3,1), rs123.1=rep(1, n),
rs157=c(2,4,2,2,2,4,4,4,2,2),
rs157.1=c(4,4,4,2,4,4,4,4,2,2), rs132=c(4,4,4,4,4,4,4,4,2,2),
rs132.1=c(4,4,4,4,4,4,4,4,4,4))
Thus, there are a few columns of basic demographic info and then the rest of
the columns are biallelic SNP info. Ex: rs123 is allele 1 of rs123 and
rs123.1 is the second allele of rs123.
1) I need to merge all the biallelic SNP data that is...
