<p>Boolean vectors in INCA are stored internally as 0/1 and are changed to "True"/blank when exported. These functions identify such a variable as Boolean and can coerce it to such.</p>


Handle data in formats used by cancer centers in Sweden, both from 'INCA'
(the current register platform, (see <http://www.incanet.se> for more information) and
by the older register platform 'Rockan' (used in the Western and Northern part
of the country).
All variables are coerced to suitable classes based on their
format.
Dates (from various formats such as with missing month or day, with or
without century prefix or with just a week number) are all recognized as
dates and coerced to the ISO 8601 standard (Y-m-d).
Boolean variables (internally stored either as 0/1 or "True"/"False"/blanks
when exported) are coerced to logical.
Variable names ending in '_Beskrivning' and '_Varde' will be character,
and 'PERSNR' will be coerced (if possible) to a valid personal identification
number 'pin' (by the 'sweidnumbr' package).
The package also allow the user to interactively choose if a variable should
be coerced into a potential format even though not all of its values might
conform to the recognized pattern.
It also contain a caching mechanism in order to temporarily store data sets
with its newly decided formats in order to not rerun the identification
process each time.
And finally, it also include a mechanism to aid the documentation process
connected to projects build on data from 'INCA'.
