a list of ratetables. If names are given, they are included as
dimnames.
dim.name
the name of the added dimension.
merge
if FALSE (default) only the intersect of all years/ages is taken.
If TRUE all possible years/ages are included (NOTE: in this case hazards are extrapolated
from earlier or later years/ages). This option only works for ratetables with dimensions
Details
This function joins two or more ratetable objects by adding a new
dimension. The cutpoints of all the rate tables are compared; if merge=FALSE
(default) only the common intervals are kept, otherwise if merge=TRUE all
intervals are added (and hazards are extrapolated).
If the intervals defined by the cutpoints are not of
the same length, a warning message is displayed. Each rate table must have
the same dimensions.
