次のような、より簡潔で一挙一動的な方法はありますか?3d配列を2次元に縮小する
x <- array(1:12, dim = c(3, 2, 2))
> x[1,,]
[,1] [,2]
[1,] 1 7
[2,] 4 10
> x[2,,]
[,1] [,2]
[1,] 2 8
[2,] 5 11
> x[3,,]
[,1] [,2]
[1,] 3 9
[2,] 6 12
# Reduce 3d array to 2d (Is there a more elegant way?)
y <- x
dim(y) <- c(nrow(y), 4)
> y
[,1] [,2] [,3] [,4]
[1,] 1 4 7 10
[2,] 2 5 8 11
[3,] 3 6 9 12
