Hi Rich,
I was looking for something that I could make general, as a latex.ftable
method for ftable objects. I realize you showed how to do this for a
particular case, but I'm having a bit of trouble translating this into
a general solution for 1 or more row variables and 1 or more col variables.
This is most likely because latex() offers a bewildering collection
of arguments I don't fully understand how to apply in this case.
Here is my current sketch, with test cases below, one of which fails...
latex.ftable <- function(object, numeric.dollar=FALSE, ...) {
cv <- attr(object,"col.vars")
rv <- attr(object,"row.vars")
ncv <- length(cv)
nrv <- length(rv)
colheads <- cv[[1]]
cgroup <- if (ncv>1) cv[[1]] else NULL
rowname <- rv[[2]]
rgroup <- if (nrv>1) rv[[1]] else NULL
latex.default(object, colheads=colheads, rowname=rowname,
cgroup=cgroup, rgroup=rgroup, numeric.dollar=numeric.dollar, ...)
}
> ft <- ftable(UCBAdmissions)
> ft
Dept A B C D E F

Admitted Male 512 353 120 138 53 22
Female 89 17 202 131 94 24
Rejected Male 313 207 205 279 138 351
Female 19 8 391 244 299 317
> str(ft)
ftable [1:4, 1:6] 512 89 313 19 353 17 207 8 120 202 ...
- attr(*, "row.vars")=List of 2
..$ Admit : chr [1:2] "Admitted" "Rejected"
..$ Gender: chr [1:2] "Male" "Female"
- attr(*, "col.vars")=List of 1
..$ Dept: chr [1:6] "A" "B" "C" "D" ...

Michael,
I think this is what you are looking for.
