ccTable_filter_range: Numerical range filter

In cleanEHR: The Critical Care Clinical Data Processing Tools

Description

Range filter can only be applied on numerical fields. For those fields which requires a range filter to be applied, one needs to set a series ranges from the broadest to the narrowest in the YAML configuration. We can set three levels (labels) of ranges, red, amber, and green. It is also OK to set only one range instead of three. The range filter will first assign a label to every data entry.

Arguments

select

the range label - "red", "amber", "green" If I give "yellow to select, it means I only want the values which is labeled as "yellow" to be in the clean table.

Details

The range in the YAML configuration file can be (l, h), [l, h], (l, h], [h, l) standing for close, open and half open intervals.
