You can't. An array is just a vector with a dimension attribute, and
vectors have to be all one type. Since in general you can't coerce
text to numbers, R coerces the numbers to text.
You probably want a data.frame if you have mixed types, or if that
doesn't have enough dimensions for you, then build things out of lists
(which is how data.frames are constructed).
