[R] question regarding cast function in reshape package with mixture of numeric and character

[Jeff Newmiller]

I am baffled. Just what do you want it to do? In melted form the data are all in one column and so are necessarily of one type... there are no mixed types to cast.

As usual, assistance here will be more useful when you follow the Posting Guide and post plain text only and give reproducible examples including dput input data and references to all packages used.
