Create a contingency table (a.k.a. cross tabulation) with Datamash

file.csv has two columns with variables, say, with dates in the first one and some names in the second one. I want to create a contingency table with dates in the left column and names in the top row. To do this I can run:

$ datamash -s crosstab 1,2 -t , < file.csv > crosstab.csv 

Note: the file is coma-separated (.csv) hence the option -t ,.

To display the cross table, I can run:

$ vd crosstab.csv
