`x`	A structured character array to be converted.
`...`	Argument in `chrvec2dl` to control split pattern.

Return a vector binary tree based on the input array.

arr2dl, chrvec2dl.

#Write the column names of datatest into a array:
arr <- dl2arr(chrvec2dl(colnames(datatest)))

#Recover the vector binary tree from character array:
