recTest-functions: Working with record test results
In alexploner/R.HDSS: Process HDSS demographic data from the INDEPTH project

Functions to combine, compress and apply record test results.

addRecTest(x, y)

compressRecTest(x)

filterOnRecTest(data, rt, failed = FALSE)

`x,y,rt`	Objects of class `recTest`
`data`	the data frame for which the record tests were performed

For addRecTest, a new recTest object that combines the results from both tests.

For compressRecTest, a reduced recTest object that only retains tests that failed at least once.

For filterOnRecTest, a subset of the original data frame passed in: if failed=FALSE, the subset of records that passed all tests; otherwise the subset of records that failed at least one test, augmented by a new column FailedTest that describes which test(s) each record failed.
