SYNOPSIS

gbbin [options]

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.
