DF

##---- Should be DIRECTLY executable !! ----
##-- ==>  Define data, use random,
##--	or do  help(data=index)  for the standard data sets.

## The function is currently defined as
function (DF) 
{
    classes <- function(x) {
        paste(class(x), collapse = ", ")
    }
    columnnames <- colnames(DF)
    columnclasses <- sapply(DF, classes)
    columnidx <- seq_along(DF)
    data.frame(ColumnName = columnnames, ColumnClass = columnclasses, 
        ColumnIndex = columnidx)
  }
