Output
Here is the report produced by the above sample program:
The previous examples in the fmtr documentation were intentionally simplified to focus on the workings of a particular function. It is helpful to also view fmtr functions in the context of a complete program. The following example shows a complete program.
The data for this example has been included in the
fmtr package as an external data file. It may be
accessed using the system.file() function as shown below,
or downloaded directly from the fmtr GitHub site here
