[R] sequencial frequency table

[Mauricio Cardeal]

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
