Recognize and Handle Data in Formats Used by Swedish Cancer Centers
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
Dates (from various formats such as with missing month or day, with or
without century prefix or with just a week number) are all recognised 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 recognised 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.
Package to handle datasets in INCA format
The package is primarly used to create a new data object of class "incadata" (inharating from class "tbl" in dplyr). All variables are coerced to suitable classes based on their format. Dates are recognised as dates (through the rccdates package), logical variables (with values "" and "True" in INCA) will be boolean, variablev with names ending in "_Beskrivning" and "_Varde" will be factors, variable with name "PERSNR" will be coerced to "pin" (by the "sweidnumbr" package) etcetera.
The package is primarly intended for use as a part of the
rcc2 package but can also be installed independently:
The package contains two vignettes. Find them after installation by
