latex tables for 3+ dimensional tables/arrays
I'm looking for an R method to produce latex versions of tables for
table/array objects of 3 or more dimensions,
which, of necessity is flattened to a 2D display, for example with
ftable(), or vcd::structable, as shown below.
I'd be happy to settle for a flexible solution for the 3D case.

How to latex tables?
Suppose I have a table constructed from structable or simply just an
object of class table. How can I convert it to a latex object? I looked
in RSiteSearch, but only found info about matrices or data frames.

For example, here is a table t2
> str(t2)
table [1:2, 1:2, 1:2] 6 8 594 592 57 ...
- attr(*, "dimnames")=List of 3
..$ Hospital : chr [1:2] "A"

justify hard coded in format.ftable
Dear all,
I haven't received any feedback so far on my proposal to make "justify" argument available in stats:::format.ftable
Is this list the appropriate place for this kind of proposal?
I hope this follow-up to my message won't be taken as rude. Of course it's not meant to be, but I'm not used to the R mailing lists...
Thank you in advance for your comments,
Best,

Grouped AND stacked bar charts possible in R?
Good day all,
My statisticians want an R procedure that will produce grouped stacked
barplots. Barplot will
stack or group, but not both. The ftable function can produce a table
of the exact form they want, but the barplot doesn't show all the
divisions we want.
For an example, here's the sample from the help file for "ftable:"
data(Titanic)
ftable(Titanic, row.vars = 1:3)

ftable and xtabs
Hoping someone can help me with xtabs and ftable. I'm trying to get a pair
of ftables (possibly more) next to each other. For example:

dunhill_lights, data = ciggs))
> dunhill_lights_xtab
dunhill_lights No Yes

Cross-tabulation of data from database
I am quite new to R, so please bear over with me if I have problems with the
R terminology.
I want to (try to) use R for some analyses within vegetation ecology, using
the vegan package. I have my data in a postgresql database, and I manage to
get them into R as a dataframe with columns for respectively: Name of the
analysed m2, Name of the species, coverage of species in the square in %. I

How can I export an ftable object in the same format that appears in R

For testing that i was using this example that is in help of this function.
## Start with a contingency table.

constructing a contingency table (ftable, table)
Dear all,
an hopefully quick table question.
I have the following data:
Two objects that are 2*9 matrix with nine column names (Dis1, ...,
Dis9) and the row names (2010,2020). The content are frequencies

Convert ftable to latex?
Dear list,
I cannot make the latex command to output a ftable objet the way I
want it. Is it posible?
I found a post in the archives saying that one should use the rgroup
and n.rgroup arguments to supply the row names, but so far I have been
unsuccessful.
This is what I have:

Suggestion: 'method' slot for format.ftable()
Dear R-developers,
I would like to suggest a 'method' slot for format.ftable() (see an adjusted
'format.ftable()' below, taken from the source of R-2.15.2).
At the moment, format.ftable() contains several empty cells due to the way the
row and column labels are printed. This creates problems (= unwanted empty
columns/rows) when converting an ftable to a LaTeX table; see an

proposal: stats::as.matrix.ftable method
Following some discussion on R-help, I'd like to propose that an
as.matrix method be added
to those available for ftable objects. The reason for this is that
there are a variety of situations
where one needs to flatten a 3+ way table, but then use that for
analysis as a matrix, not just for
pretty-printing. There is an as.table method to turn the result back to
a table, but an as.matrix

Woolf's test, Odds ratio, stratification
Just a general question concerning the woolf test (package vcd), when we have
stratified data (2x2 tables) and when the p.value of the woolf-test is
below 0.05 then we assume that there is a heterogeneity and a common odds
ratio cannot be computed?
Does this mean that we have to try to add more stratification variables
(stratify more) to make the woolf-test p.value insignificant?

data frame method for as.table()
Hello,
Currently it's possible to convert an object of class table to a data frame
with as.data.frame.table(), but there's no ready-made function, AFAIK, to do
the reverse operation, i.e. conversion of a data frame to a table.
Do you think it would be a good idea to add a data.frame method to
as.table(), to allow such conversions?
The idea is that if `x' is a table and `y <-

List of occuring values
Dear all,
ftable produces a list of the frequencies of all occuring values.
But how about the occuring values?
How can I retrieve a list of occuring values?
How can I retrieve a table with both the list of occuring values and their respective frequencies?

Hi All,
I'm new at programming in R.
Some functions create objects for which extractor functions are written
to pull out some partial result.
I wish to extract partial results from functions without extractor
functions:
for example, to pass a vector of results to another function.
Even after looking at V&R S Programming I don't see a general approach.
Specifically, how would I
