gets the percentiles for global indices
gloperc( vals, percentiles = c( 0.5, 1, 2, 5, 95 ),
type = c( "quantile", "(i-1)/(n-1)", "i/(n+1)", "i/n" ) )table with global indices for control subjects
percentiles at which to calculate cutoff values
see wtd.quantile for a list of different options
percentiles for global indices
gets the percentiles for global indices. This function works in conjunction with vfstats. In vfstats all global indices refering to mean must start with m and all refereing to standard deviation must start with s, otherwise gloperc won't calculate the cutoff values correctly
