Thank you so much. I have yet another problem that I could not resolve from
the documentation. I want to get line breaks for long variable names.
Here's an example:
Gender<-sample(c("m","f"),20,replace=TRUE)
Education<-rnorm(20,13)
label(Education)<-"Years of\nEducation"
summary(Gender~Education,method="reverse")
Descriptive Statistics by Gender
Descriptive Statistics by Gender
+---------+--------------+--------------+
| |f |m |
| |(N=12) |(N=8) |
+---------+--------------+--------------+
|Years of |12.5/12.9/13.9|12.5/12.9/13.5|
|Education| | |
+---------+--------------+--------------+
As you can see, it works fine for the printing in R, but when I submit this
table to the latex-function the \n gets removed. How can I prevent this?
Regards
Erich

Instead of NA put '' or "" and it should work.
