VALIDATA(1) |STAT February 3, 1987
NAME
validata - validate and report columnar file consistency
SYNOPSIS
validata
DESCRIPTION
_▶08◀v_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀a reads a file from the standard input and for each column in
its input, reports statistics about the data type of fields (whether a
column contains alphanumeric strings, integers, real numbers, or
something else). _▶08◀v_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀a also reports the maximum and minimum values
of the columns; _▶08◀v_▶08◀a_▶08◀l_▶08◀i_▶08◀d_▶08◀a_▶08◀t_▶08◀a is useful to check data files for consistency
before input to some data analysis program because it detects missing
columns or columns of the wrong type, such as non-numeric input.
EXAMPLE
series 1 100 | dm x1 RAND "x1^.5" | validata
Col N NA alnum alpha int float other type min max
1 100 0 100 0 100 100 0 int 1 100
2 100 0 0 0 0 100 0 float 0.0123 0.9836
3 100 0 10 0 10 100 0 float 1 10
