Hi,
I used this command to produce a table:
(tab1 = ftable(SEX, ESTCIV, Q1))
Q1 B L M N
SEXO ESTCIV
F A 11 13 4 2
E 1 0 0 0
M A 5 0 3 1
E 0 0 0 0
but I need something like:
SEXO ESTCIV B L M N
F A 11 13 4 2
F E 1 0 0 0
M A 5 0 3 1
M E 0 0 0 0
How can I get it?
I need this format to use ordinal logistic regression and I have many tables.
Thanks,
Silvano.

Hi, Try: library(reshape2) dcast(as.data.frame(tab1), SEX+ESTCIV~Q1,value.var="Freq") ##not tested. A.K.

What does your original data look like? I seems to me that it would be better to give us that information since you may not want to use ftable() at all. Ideally you should give us the original data or a sample of it. If it's confidential just replace the actual values with fake data. The structure of the data is more important than the values. Please use dput() (see ?dput for information) to supply the data. Just do : dput(mydata) and then paste the result into the email.

If is for display, the answer will be to look at the code for `print.ftable` (which eventually passes its arguments to `format.ftable`. If it is for creating something other than an ftable (such a data.frame or character-matrix), then you will probably need to coerce the ftable to a matrix to get the entry values and then extract the row labels from the 'tab1'-object with: attr(tab1, "row.vars") and `rep` them approriately. Or you could work with the output from format(ftable(tab1))[ ,1:2]. cbind( format(ftable(Titanic), quote=FALSE)[ ,1:3], format(ftable(Titanic), quote=FALSE)[ ,5:6]) [,1] [,2] [,3] [,4] [,5] [1,] " " " " " " " No" "Yes" [2,] "Class" "Sex " "Age " " " " " [3,] "1st " "Male " "Child" " 0" " 5" [4,] " " " " "Adult" "118" " 57" [5,] " " "Female" "Child" " 0" " 1" [6,] " " " " "Adult" " 4" "140" [7,] "2nd " "Male " "Child" " 0" " 11" [8,] " " " " "Adult" "154" " 14" [9,] " " "Female" "Child" " 0" " 13" [10,] " " " " "Adult" " 13" " 80" [11,] "3rd " "Male " "Child" " 35" " 13" [12,] " " " " "Adult" "387" " 75" [13,] " " "Female" "Child" " 17" " 14" [14,] " " " " "Adult" " 89" " 76" [15,] "Crew " "Male " "Child" " 0" " 0" [16,] " " " " "Adult" "670" "192" [17,] " " "Female" "Child" " 0" " 0" [18,] " " " " "Adult" " 3" " 20"> > I need this format to use ordinal logistic regression and I have many tables.That makes me think using ftable is the completely misguided approach. You should describe in more detail you plans to use ordinal logistic regression. I'm also wondering if you have used attach(). It would make more sense to keep these variables in a dataframe. Almost all regression functions expect input in the form of a normalized dataframe rather than in separate variables of aggregated counts.> (tab1 = ftable(SEX, ESTCIV, Q1)) > > Thanks, > > Silvano. > > --- > Este email est? limpo de v?rus e malwares porque a prote??o do avast!
