Dear R users...
I'd like to change this character vector, "zz",
zz <- c("12","56","89")
to the following numeric matrix.
[,1] [,2]
[1,] 1 2
[2,] 5 6
[3,] 8 9
Actually, "zz" vector has a long length.
Any comments will be greatly appreciated.

pieces <- strsplit(zz, "") # look at what pieces looks like
my.data <- as.numeric(unlist(pieces))
my.matrix <- t(matrix(my.data, nrow=2))
my.matrix
[,1] [,2]
[1,] 1 2
[2,] 5 6
[3,] 8 9
