Make 2D-spline fits of incidences
Description
Produces two dimensional (2D) spline fits of cancer incidence versus age and calendar year, with interactions. In conjunction with person years (PY) at risk, this is used in csd() to produce expected numbers of cases under a null hypothesis that prior cancers do not impact subsequent cancer risks.
Usage
mk2D(seerSet, knots=5, write=FALSE, outDir="~/Results",txt=NULL,secondS=NULL)Arguments
seerSet |
Object of class seerSet, i.e. output list of seerSet(). |
knots |
Base number of knots; overrides are in place for some cancers. |
write |
TRUE = write 2D fits to files. The fits can be >300 MB and take >60 seconds to write, so leave FALSE unless you need it. |
outDir |
Folder that will hold the output files. |
txt |
Additional text to distinguish files with different cancer lists. This may be useful during spline fit development. |
secondS |
Charcter vector of second cancers of interest (note: I often capitalize the final S of vectors of Strings). |
Value
The input seerSet with an additional data frame D added to this list. D holds background/expected incidences over a 1-year resolution age-year grid.
