Your question is not well formed: do you want a list or a string
(totally different things)? Or even more likely, a character vector?
What do you have now: is it really an array (=matrix) or is it the
data.frame it looks like?
If it's a matrix:
x <- matrix(letters[1:8], ncol = 2)
x <- as.vector(x) # Character Vector
paste(x, collapse = "") # String
If it's a data frame with factors:
x <- data.frame(matrix(letters[1:8], ncol = 2))
as.character(unlist(x)) # omit as.character() if you actually have
character elements and not factors.
