Convert table to data frame in R

as.data.frame.matrix()

X = c(1,1,1,2,2,2,3,3,3) Y = c('A','B','A','B','A','B','A','B','A') 

tbl <- table(X, Y, useNA='ifany') df.tbl <- as.data.frame.matrix(tbl) 

> tbl    Y X   A B   1 2 1   2 1 2   3 2 1 > df.tbl   A B 1 2 1 2 1 2 3 2 1 > class(tbl) [1] "table" > class(df.tbl) [1] "data.frame"
