counting number of cells in a column with a given value

Hi,

I'd like to count the number of cells in a column with zero as the value (or another arbitrary number).  Ideally, the results would be outputted as a list of counts.  Can someone point me in the right direction?  Thank you.

Regards,

Will

Something like this should get you close:

dt << Current Data Table();

cols = dt << Get Selected Columns();

counts = NewTable("Counts for "||char(dt<

for(i = 1, i <= NItems(cols), i++,

     r = dt << Select Where( ascolumn(eval(cols)) == 0 );

     counts << AddRows({:Column = column(dt,cols)<< Get Name, :Count = NItems(r)});

);

I didn't test this.

If all you want to know is how many times each value occurs in a given column, you could simply use:

Tables menu -> Summary

Enter the column in the field for 'Group'

The resulting table should have 2 columns, the first being all the values that occur, and the second being the number of times each occurs.

I would think that the easiest solution would be to simply use proc freq outputting the results to a file and then post-processing the output file for whatever criteria you need.
