v input view prefix column name prefix (default: x)
Transpose returns a "flipped" view in which all rows and columns have been excchanged. The column names in the resulting view will be numbered from zero, and prefixed with the specified prefix.
This operator only works for views where all columns are of the same type.
Example:set v [view {A B} def {1 2 3 4 5 6}]
view $v transpose
x0 x1 x2 0 1 3 5 1 2 4 6
(transpose is defined in Ratcl)
