.SH NAME
gbquant \- Print quantiles of data distribution
.SH SYNOPSIS
.B gbquant
[\fI\,options\/\fR]
.SH DESCRIPTION
Print distribution quantiles. Data are read from standard input. If no
\fB\-x\fR or \fB\-q\fR options are provided, a quantiles table is plotted. The number
of quantiles can be chosen with \fB\-n\fR. The option \fB\-x\fR #1 prints the quantile
associated with the value #1, while \fB\-q\fR #2 print the value associate with
the quantile #2. Of course #2 must be between 0 and 1. Multiple values
can be provided to \fB\-x\fR or \fB\-q\fR, separated with commas. With \fB\-w\fR #1,#2 all
the observations inside the quantile range [#1,#2) are printed. If more
columns are provided with option \fB\-t\fR, the specified action is repeated on
each column. Without \fB\-t\fR, columns are pooled unless \fB\-w\fR is specified, in
which case all rows whose first element is inside the range are printed.
A different column for sorting can be specified with option \fB\-W\fR. If 0 is
specified, the cut is applied with respect to all columns. With option \fB\-Q\fR
each entry is replaced with the quantile range it belongs to, with respect
to the distribution obtained from the entries in its column.
