stattable.funs {Epi} | R Documentation |
These functions may be used as contents
arguments to the
function stat.table
. They are defined internally in
stat.table
and have no independent existence.
count() ratio(d,y,scale=1, na.rm=TRUE) percent(...)
d, y |
numeric vectors of equal length (d for Deaths,
y for person-Years) |
scale |
a scalar giving a value by which the ratio should be multiplied |
na.rm |
a logical value indicating whether NA values should
be stripped before computation proceeds. |
... |
a list of variables taken from the index argument
to stat.table |
When used as a contents
argument to stat.table
, these
functions create the following tables:
|
returns a contingency table of counts. |
|
returns a table of values
scale * sum(d)/sum(y) |
|
returns a table of percentages ratio(d,y,scale=1, na.rm=TRUE)
of the
classifying variables. Variables that are in the index
argument to stat.table but not in the call to
percent are used to define strata, within which the
percentages add up to 100. |
