Description Usage Arguments Value Examples

Find the marker index corresponding to the peak of the pleiotropy trace in a tibble where the last column contains log likelihood values and the first d columns contain marker ids

1	find_pleio_peak_tib(tib, start_snp)

`tib`	a (d+1) column tibble with first d columns containing marker ids and the last containing log likelihood values. Typically this is the output from 'scan_pvl'.
`start_snp`	positive integer, from the two-dimensional scan, that indicates where the scan started on the chromosome

positive integer indicating marker index for maximum value of log lik under pleiotropy

marker1 <- rep(paste0('SNP', 1:3), times = 3)
marker2 <- rep(paste0('SNP', 1:3), each = 3)
loglik <- runif(9, -5, 0)
