Arguments pseudo-function
The Arguments pseudo-function enables the use
of analysis functions that take multiple arguments.
Arguments(...)
... |
Arguments to pass to the analysis function. |
The arguments to Arguments
are evaluated in full, then those which are length n are subsetted for
each cell in the table.
If no analysis variable has been specified, but Arguments() has been, then
the analysis function will be called with arguments matching those
given in .... If an analysis variable was specified, it will
be inserted as an unnamed first argument to the analysis function.
The Arguments() entry will not create a heading.
Only one Arguments() specification may be active in any
term in the tabular formula.
This is a “pseudo-function”: it takes the form of a function call, but is
never actually called: it is
handled specially by tabular.

a multiple argument analysis function.
# This is the example from the weighted.mean help page wt <- c(5, 5, 4, 1)/15 x <- c(3.7,3.3,3.5,2.8) gp <- c(1,1,2,2) tabular( (Factor(gp) + 1) ~ weighted.mean*x*Arguments(w = wt) )
