Re: [R] Cross tabulation with top one variable and side as multiple variables
They do not match because xtabs() in R produces a multidimensional array (one dimension for each variable). Looking at your spreadsheet on nabble, it appears that SPSS is just creating 4 crosstabulations with TREND against each of the other variables. That is easily done in R, but for tested code, you need to give us reproducible data using dput(). I get an error using read.spss() on your uploaded file. You should also read some of the extensive free documentation available on R. The ftable() function creates a two dimensional representation of that 5-dimensional array. But your spreadsheet is just a stack of two-dimensional tables. You could get there with the margin.table() function, but unless you really need the 5-dimensional array, you probably want something more like: rowvars - c(AGET, SEXT, EDUCRT, JOBRT) table.lst - lapply(rowvars, function(x) xtabs(~x+TREND)) That would give you a list containing a crosstabulation table between each of the variables and TREND. A spreadsheet with 2000 tables seems a bit unwieldy so you might want to give some thought to what you really want as output. - David L Carlson Department of Anthropology Texas AM University College Station, TX 77840-4352 -Original Message- From: R-help [mailto:r-help-boun...@r-project.org] On Behalf Of jagadishpchary Sent: Thursday, June 18, 2015 1:46 AM To: r-help@r-project.org Subject: Re: [R] Cross tabulation with top one variable and side as multiple variables I think my explanation in the post is not giving the full details on the job to be done.

[R] Cross tabulation with top one variable and side as multiple variables
Hi: I have a huge data with lot of variables and I need to check the trend variations from year to year. In order to do so, I have to cross tabulate the year variable as top (constant) and all the remaining variables as side (attached the cross tabulation report). I have searched the forums but the syntax I could find for cross tabulation is between 2 or 3 variables. So i would request to provide a code which can print the data in the same way as in the attached. http://r.789695.n4.nabble.com/file/n4708379/Untitled.png -- View this message in context: http://r.789695.n4.nabble.com/Cross-tabulation-with-top-one-variable-and-side-as-multiple-variables-tp4708379.html Sent from the R help mailing list archive at Nabble.com. __ R-help@r-project.org mailing list -- To UNSUBSCRIBE and more, see 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.
Re: [R] Cross tabulation with top one variable and side as multiple variables
There are two issues here... calculation and presentation. The table function from base R can work with many variables. If your data set is so large that you have problems with memory then you could investigate data.table or sqldf packages, which perform the computations but do not present the data in cross tabulation form. You could use table or perhaps the tables package to render the data into the desired form. --- Jeff NewmillerThe . . Go Live... DCN:jdnew...@dcn.davis.ca.usBasics: ##.#. ##.#. Live Go... Live: OO#..

Re: [R] Cross tabulation with top one variable and side as multiple variables
We probably should have a better idea of what the raw data looks like and perhaps a bit better idea of what the analyis is to show. Have a look at http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example and http://adv-r.had.co.nz/Reproducibility.html for some suggestions. In particular see the discussion about dput() for the best way to provide sample data to the help list.
