I need to perform a number of checks on the values in a large table. Currently I implement the checks in code in a script. I find it can be cumbersome if I want enable or disable certain checks, as I need to comment out or use a if
. Looking at my checks, they appear all to be of a similar structure: element-wise operations on the columns of the table. So I thought I would try to implement the checks as a list of anonymous functions stored in a spreadsheet. This way I could easily enable/disable with a column value.
I get stuck for a while (between 22:35 and 31:00), where I think isempty
operates element-wise on an array when it always operates on the entire array and returns a scalar. Also sound quality is reduced from there to the end.
