compFscore: F score computation
In jmonlong/sQTLseekeR: Splicing QTL discovery tool

Compute the F score, max diff ratio difference.

1	compFscore(geno.df, tre.dist, tre.df, svQTL = FALSE)

`geno.df`	a data.frame of one row with the genotype information for each sample.
`tre.dist`	a distance object from the transcript relative expression.
`tre.df`	a data.frame with the transcript relative expression.
`svQTL`	should svQTL test be performed in addition to sQTL. Default is FALSE.

a data.frame with columns:

`F`	the F score.
`nb.groups`	the number of groups created by the genotypes.
`md`	the maximum difference in splicing ratios between genotype groups.
`tr.first, tr.second`	the two transcripts that change the most.
