NAME

       gbbin - A program to bin data

SYNOPSIS

       gbbin [options]

DESCRIPTION

       Compute  binned  statistics.  Data  are read from standard input as records (X,Y1,Y2,...).
       Equipopulated bins are built with respect to the first field X.  Option  -O  decide  which
       statistics  are printed for each bin. With options -x, -y or -c elements in different bins
       are split in different columns.

OPTIONS

       -n     set the number of equipopulated bins (default 10)

       -w     min,max set manually the binning window. Ignored with -x,-y and -c

       -O     set the output with a comma separated list of variables: xmean, xmin,  xmax,  xstd,
              xmedian,  ymean, yadev, ystd, yvar, yskew, ykurt, ymin, ymax, ymedian, num (default
              xmean, ymean)

       -c#    the values in column # are split in different columns; # can be a  comma  separated
              list of columns

       -x     equivalent to -c 1

       -y     equivalent to -c 2

       -F     specify the input fields separators (default " \t")

       -v     verbose mode

EXAMPLES

       gbbin -n 20 < file
              split  the  records  (line)  in 20 bins according to first field. Print the average
              value of the bin entries for each column. If 'file' has 3 columns, the  output  has
              twenty rows and three columns.

       gbbin -O ymedian < file
              bin  the  records with respect to the first value and print the median value of the
              other columns in each bin

       gbbin -c 3 < file
              the binned values of the third columns are printed on separate columns. The  output
              has ten columns.
