This function removes the LogRatio column of the snpInfo data.frame. Then compute the copy number of each SNP having its quartet intensities. And return the snpInfo data.frame with the newly computed LogRatio.

1	fromQuartetToSnp(quartetInfo, snpInfo, cIntensity="quartetLogRatio", nLog=1)

`quartetInfo`	A table containing the quartet intensities and other quartet information. It must have a column called : fsetid.
`snpInfo`	A table containing snp information.
`cIntensity`	A vector containing the names of the quartet information to be aggregate. For example quartetLogRatio.
`nLog`	The position of the field which will be named LogRatio in the snpInfo data.frame. For example if cIntensity = c("a", "b") and you want b to be considered as the LogRatio you should set nLog=2
