R help - Jan 2007 - sequencial frequency table

Hi.

I have the data frame xyz below and I?d like to perform a sequencial 
frequency table using some unique function instead of making 3 different 
one-by-one table (table x, table y and table z). But I?can?t figure out 
the correct way.

x <- c(2,3,2,4)
y <- c(3,1,1,1)
z <- c(4,2,1,4)
xyz <- as.data.frame(cbind(x,y,z))

freq <- function(x){
table(x)
}

freq(xyz)

Thank you,
Mauricio

Is that what you want?

$x

2 3 4 
2 1 1 

$y

1 3 
3 1 

$z

1 2 4 
1 1 2 


See ?lapply if so.
