Compare whether x > y.

Like all other FExpr operators, the greater-than operator is elementwise: it produces a column where each element is the result of comparison x[i] > y[i].

If x or y are multi-column expressions, then they must have the same number of columns, and the > operator will be applied to each corresponding pair of columns. If either x or y are single-column while the other is multi-column, then the single-column expression will be repeated to the same number of columns as its opponent.

The greater-than operator can be applied to columns of any type, and the types of x and y are allowed to be different. In the latter case the columns will be converted into a common stype before the comparison.



The arguments must be either FExprs, or expressions that can be converted into FExprs.


An expression that evaluates x > y. The produced column will have stype bool8.
