Hello,
I have a dataframe (var_1, var_2, ..., var_n) and I would like to export summary
statistics to Latex in the form of a table. I want specific summary statistics
by crossing numerous variables 2x2 AT ONCE. In each cell I would like sometimes
to have the median (Q1 - Q3), or frequency and proportion, etc. CrossTable,
xtab, etc... do not allow for multiple 2 by 2 crosstabulation. The table would
look like this:
var_1 var_2 var3, ...
var_1 a b c
var_2 d e f
var_3 .. ... ...
with a, b, c, ... the results of each crosstabulation. I have continuous and
categorical variables.
Any idea?
Thank you very much,
David.

You probably have a clear idea what "summary statistics by crossing numerous variables 2x2 AT ONCE" means but I do not. It is possible that the describe.formula in Hmisc or the summaryBy function in the doBy package may be helpful, but that is merely a guess.> > Thank you very much, > > David. > > > > [[alternative HTML version deleted]] > > ______________________________________________ > R-help at r-project.org mailing list > https://stat.ethz.ch/mailman/listinfo/r-help > PLEASE do read the posting guide http://www.R-project.org/posting-guide.html > and provide commented, minimal, self-contained, reproducible code.David Winsemius, MD West Hartford, CT
