R help - Jul 2009 - how to get R to print only one column per line when outputting a matrix?

Hi,

I'm trying to make it easier for my survey evaluators to read the
results of my survey analysis. To that end, I'd like to suppress R's
habit of filling every line up to width columns.  How do I do that?

For instance, using 'print()', R outputs something like:

     [,1]                     [,2]
var2 "someshortname" "someothershortname"
r    0.3341755                0.3275274
N    136                      136
     [,3]
var2 "somereallyreallyreallyreallyreallylongname"
r    0.323306
N    136
     [,4]
var2 "someotherreallyreallyreallyreallyreallylongname"
r    0.3121291
N    101
----

How can I get it to place every column on a new line to avoid
confusing the reader?

I read the help for print, print.default, format, cat, and
options(width) and wasn't able to find an answer.

Thanks!

It looks like you are printing a matrix and that you want to print all  
rows of the first column before all rows of the second column. Apply  
should do it. Assume the matrix is named "AA"

apply(AA, c(2,1), cat, "\n")   # the \n is the line-feed character

But you have not offered the code that produced this.
