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.
