[R] question regarding cast function in reshape package with mixture of numeric and character
Hi, I am trying to process some data frame with cast function to unwind the stacked variables. I have no problem using cast when the values are all numeric based on the following format: cast(df,subject~v1+v2+v3....,value = "value",fun.aggregate = mean, fill "NA") However, I am getting some trouble when the "value" variable has a mixture of numeric and character. I played around dropping off the fun.aggregate = mean option, but it use the default: which is the length and not what I want. I am wondering if there is anyway of doing this? Many thanks, -Jack [[alternative HTML version deleted]]

[R] question regarding cast function in reshape package with mixture of numeric and character
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. --------------------------------------------------------------------------- Jeff Newmiller The ..... .....
